Polar Covalent Bonds and Nonpolar Covalent bonds, Ionic Bonding - Types of Chemical Bonds
 
12:14
This chemistry video tutorial provides a basic introduction into the types of chemical bonds such as polar covalent bonds, nonpolar covalent bonds and ionic bonds. It discusses the difference between ionic bonding and covalent bonding. Ionic bonds can be identified by looking for a metal combined with a nonmetal. Covalent bonds typically occur among 2 or more nonmetals. Covalent bonding involves a sharing of electrons and ionic bonding forms as a result of a transfer of electrons from the metal to the nonmetal producing ions with opposite charge which are attracted to each other. The electrostatic force of attraction produces the ionic bond that holds the cations and anions together. Polar covalent bonds have unequal sharing of electrons between the atoms where as nonpolar covalent bonding have a relatively equal sharing of electrons between the atoms attached to the bond. Polar covalent bonds typically have an electronegativity difference of 0.5 or more where as nonpolar covalent bonds have a value difference of 0.4 or less. This video contains plenty of examples and practice problems.

Naming Covalent Molecular Compounds
 
10:46
We'll learn how to write names for compounds that are made of two nonmetals, sometimes called binary compounds. Binary compounds made of two nonmetals are called covalent or molecular because the elements are held together with covalent bonds, and they make molecules. In order to name them, we use the element name for the first element in the chemical formula, and then we use the -ide name for the second name in the chemical formula. Greek prefixes to show the number of atoms of each element, and these are put in front of the element names.

What Are Covalent Bonds | Chemistry for All | FuseSchool
 
05:53
Learn the basics about covalent bonds, when learning about properties of matter. When similar atoms react, like non-metals combining with other non-metals, they share electrons. This is covalent bonding. Non-metals have shells of electrons that are normally half or more than half full of electrons. Since they have a strong attraction for a few additional electrons, it is energetically unfavourable for any of them to lose electrons, so they share electrons by overlapping orbitals. This makes a bonding orbital, or covalent bond, that contains two or more electrons. Covalent bonds can be represented by a dot and cross diagram. These diagrams show only the valence electrons. Covalent bonds are directional, which means they are in a fixed position. The overlap between orbitals mean that the atoms in covalent bonds are very close, and make covalent bonds strong. There are two kinds of covalent structure - small molecules, like water, and giant compounds, like diamond. The electrons in the bonds are evenly shared, which means the bonds are not polarised; there is little attraction between molecules, and forces between molecules are weak. Compounds made from small covalent molecules have low melting and boiling points and are volatile. They also don’t conduct electricity. Carbon and silicon tend to form giant covalent compounds. These bond in the same way, but instead of forming small molecules with one or two bonds, they form four, make up huge lattices or chains of many many linked up atoms. Diamond is a common example, and is made up of Carbon. These compounds have very high melting and boiling points because you have to break covalent bonds rather than intermolecular forces to make them free enough to act like liquids or gases. The covalent bonds hold them rigidly in place in the giant lattice. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Ionic vs. Molecular
 
08:52
To see all my Chemistry videos, check out http://socratic.org/chemistry How can you tell the difference between compounds that are ionic and molecular (also known as covalent)? It has to do with the elements that make them up: ionic compounds are made of metals and nonmetals, and molecular (or covalent) compounds are made of nonmetals. We'll learn how they bond differently: in covalent compounds, the atoms share electrons, and in ion compounds, atoms steal electrons and then opposite charges attract. Ionic and molecular (covalent) compounds also look different at the microscopic level: covalent and molecular compounds exist in molecules, while ionic compounds are organized in lattice structures.

4.2 Describe how the covalent bond is formed via electron sharing [SL IB Chemistry]
 
04:42
Atoms may share electrons to obtain a full outer shell with other atoms. The resulting molecules are more stable. Atoms may share one electron each = covalent bond. Sharing 2 each is a double bond, 3 each is a triple bond. If one atom shares 2 electrons and the other shares none that is called a dative (or coordinate) covalent bond. The hydronium ion, ammonium ion and carbon monoxide all contain a dative covalent bond. Pyro's arm grew back at respawn!

Ionic and Covalent Bonds, Hydrogen Bonds, van der Waals - 4 types of Chemical Bonds in Biology
 
08:50
There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths. In Chemistry, we think of Ionic Bonds and Covalent bonds as having an overlapping range of strengths. But remember, in biochemistry, everything is happening in the context of water. This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” Related Chemistry video: Ionic Bonds vs Covalent Bonds http://bit.ly/2cUG6C8 Our series on Biology is aimed at the first-year college level, including pre-med students.

How to Draw Covalent Bonding Molecules
 
09:17
http://www.sciencetutorial4u.com This video explains how to draw covalent molecules and compounds. Contents: 0:08 Introduction 0:39 H2 1:25 HCl 2:23 Cl2 3:18 CH4 4:27 NH3 5:37 H2O 6:52 O2 7:57 N2 Thank you for watching. Please like, subscribe and share this video: https://youtu.be/_v8C1W0ChVM INTRODUCTION 0:08 Covalent bonding happens between non-metals. The electrons are shared between the non-metal atoms. This bonding allow atoms to have full outer shell of electrons. Only the electrons in the outer shell take part in the bonding. The number of electrons in the outer shell can be found out using the group in the periodic table. H2 0:39 Hydrogen is in group 1 so it has one electron in the outer shell. Hydrogen molecules have single bond which means they have two electrons in the overlap. HCl 1:25 Chlorine is in group 7 so it has seven electrons in the outer shell. HCl has single bond so it has two electrons in the overlap. Cl2 2:23 Chlorine is in group 7 so it has seven electrons in the outer shell. Cl2 (Chlorine molecule) has single bond so it has two electrons in the overlap. CH4 3:18 Carbon is in group 4 so it has four electrons in the outer shell. Methane has four single bonds. NH3 4:27 Nitrogen is found in group 5 so it has 5 electrons in the outer-shell. The Nitrogen atom is surrounded by three Hydrogen atoms, each providing one electron in the sharing (overlap). So Ammonia has 3 single bonds. H2O 5:37 Oxygen is found in group 6 so it has 6 electrons in the outer shell. Water has 2 single bonds. O2 6:52 Oxygen molecules have double bonds. Oxygen atom is found in group 6 so it has 6 electron in the outer shell. Therefore, in the overlap there are 2 pairs of electrons (which is 4 electrons in the overlap). This leads O2 molecules to have one double bond. N2 7:57 Nitrogen molecules have triple bonds. Nitrogen is found in group 5 so it has 5 electrons in the outer-shell. In the overlap, there are 3 pairs of electrons which are 6 electrons in the overlap. This causes Nitrogen molecules to have one triple bond.

Chemistry: What is a Covalent Bond? (Polar and Nonpolar) Covalent bonds are one of the 3 main types of intramolecular forces, along with ionic bonds and metallic bonds. Covalent bonds are the result of atoms sharing their valence electrons. Covalent bonds can be polar or nonpolar, depending on the electronegativies of the atoms involved in the bond.

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
 
09:46
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

What Are Giant Chemical Structures  | Chemistry for All | FuseSchool
 
02:31
Learn the basics about the differences between different chemical structures, including giant covalent, giant ionic and metallic structures. There are numerous materials and substances that possess giant chemical structures. Some are common: like the grains of sand on the beach; the microprocessors in our computers; the graphite in our pencils, the magnesium oxide found in the cement on our buildings; the salt we put on our food; the metals found almost everywhere; and the precious gemstone diamond. These substances are vastly different and this is due to the bonding and the arrangements of chemicals atoms, or ions. Sand, graphite, and diamond are all examples of giant covalent structures. The bonding between the atoms is covalent, but the arrangements of the atoms can be different. Sand contains silicon atoms covalently bonded to oxygen atoms. It has four oxygen atoms bonded in a tetrahedral arrangement around each silicon atom. Diamond has a very similar structure to sand, where all of the carbon atoms are joined by covalent bonds in a tetrahedral arrangement. In graphite the carbon atoms are bonded in hexagonal sheets and have intermolecular forces holding the sheets together. All of the atoms are chemically joined by covalent bonds in sand, diamond and graphite and so these materials have very high melting points because a lot of energy is required to break the bonds between the atoms. They are very hard substances. Diamond is one of the hardest substances in the world, but graphite is quite soft. These layers peel away when our pencils make a mark on paper because the forces holding the layers together are intermolecular and are quite weak. So when you are writing with a pencil, you are actually transferring sheets of carbon. The structure of these materials also determines their electrical conductivity. Diamond does not conduct electricity at all, because its electrons are locked up in covalent bonds; whereas graphite contains free electrons and so can conduct. Silicon is found in semi-conductors and it through adding other elements, called ‘doping’, that it allows partial conductance, which has applications in computing. Table salt (sodium chloride) and magnesium oxide are examples of giant ionic lattices. Ionic bonds form when a metal reacts with a non-metal. Metals form positive ions; nonmetals form negative ions. Ionic bonds are the electrostatic forces of attraction between these oppositely charged ions. Giant ionic structures also have exceptionally high melting points, because the electrostatic interactions between the ions are very strong. Giant ionic lattices, when in the solid state, do not conduct electricity because their ions are fixed in the lattice.This lattice structure is lost when the solid is melted, freeing up ions which can then conduct electricity. The final giant structures we consider in this video are metals. These all share the same structure, whereby electrons in the outer shells of the metal atoms are free to move. The metallic bond is a force of attraction between these free electrons and the positively charged metal ions. Metallic bonds are strong, so metals maintain a regular structure and usually have high melting and boiling points. In addition to this, metals also have other common properties; they conduct heat and electricity because of the free electrons ability to move. Free electrons also allow the metal ions to slide past one another, and so can be hammered into shapes; this is called ‘malleability.’ The ease at which a metal can be pulled into wires depend on how ductile it is.

Covalent Bonding in Water, Methane, Ammonia & Hydrogen Fluoride | Chemistry for All | FuseSchool
 
05:16
In this video we will look at covalent bonds in methane, ammonia, water and hydrogen fluoride. They are small, covalently-bonded molecules. The atoms within them share electrons because they have half full or more than half full valence shells of electrons: they are non-metals. Methane is a fuel, ammonia is used in household cleaners, water is a drink and the essence of life, and hydrogen fluoride is used to etch glass. The bonding in methane, ammonia, water and hydrogen fluoride shows a pattern: methane is carbon bonded to four hydrogen atoms; ammonia is nitrogen bonded to three hydrogen atoms; water is oxygen bonded to two hydrogen atoms, and hydrogen fluoride is fluorine bonded to just one hydrogen atom. Carbon, nitrogen, oxygen and fluorine appear in the periodic table in this order, moving along the second row from left to right. Carbon has four out of eight electrons in its outer shell, so makes four covalent bonds. Nitrogen has five out of eight electrons in its outer shell, so can make three covalent bonds to make the shell full. Oxygen has 6 electrons in its outer shell. It can bond with two hydrogen atoms to share 2 more electrons. It now has a full outer shell of 8 electrons. Ammonia has two electrons, called a lone pair of electrons, occupying the fourth position. These electrons take up space. Because electrons are negatively charged, lone pairs repel bonds even more strongly than bonds repel each other. This makes ammonia less symmetric than methane. The water molecule is bent in shape. Oxygen has two lone pairs. Negatively charged lone pairs are slightly attracted to the hydrogen atoms, so there is a weak attraction between molecules. Forces between molecules are a little stronger in water than in ammonia or methane. Water is liquid at room temperature and pressure, whilst ammonia a gas that is easily liquefied, and methane is a gas. Intermolecular forces are normally very weak in covalent compounds, but in water they are just strong enough to keep it liquid. A bit more energy is needed to overcome these forces and boil it. If water were not a liquid, life as we know it would be completely different! Ethanol contains carbon and oxygen bonding. The carbon atoms always form four bonds and the oxygen forms two. Remember, carbon forms 4 bonds, nitrogen forms 3 bonds and has one lone pair of electrons, and oxygen forms two bonds and looks bent.

025 - Covalent Network Solids In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four valence electrons and can create three-dimensional shapes. Silicon crystals act as semiconductors and can be either n-type or p-type doped to increase their effectiveness. Do you speak another language?

How Does Water Bond - Covalent Bonds | Chemistry for All | FuseSchool
 
02:40
Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

This chemistry video tutorial explains the difference between elements, atoms, molecules, and ions. It also explains how to distinguish ionic and molecular compounds also known as covalent compounds. Atoms are electrically neutral and contain equal number of protons and electrons. Ions have a net charge and contain a different number of protons and electrons. Positively charged ions are known as cations and negatively charged ions are known as anions. Atoms and Ions have the same number of neutrons. A molecule is particle consisting of multiple atoms. Pure elements are substances composed of one type of atom where as a compound is made up of different types of atoms. Ionic compounds consist of metals and nonmetals and contain ions with charges. Covalent compounds or molecular compounds usually consist of nonmetals.

We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: [email protected]): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne. Connect with Atomic School on social media: http://facebook.com/AtomicSchool http://twitter.com/AtomicSchools http://instagram.com/AtomicSchools Video transcript: Let's do a thought experiment. Imagine a box filled with hydrogen atoms. Like billiard balls on a pool table, atoms actually move, and they do it in straight lines until they hit something … like another hydrogen atom. Oh! See that? They stuck together. They’re not separate hydrogen atoms any more, but a pair of hydrogen atoms moving together. There goes another pair. 4.1 When atoms join up like this, scientists call it a molecule. And they call the join between them a chemical bond. Here comes another hydrogen atom crashing into the hydrogen molecule. But this time it doesn’t stick. Instead it just bounces off. Hydrogen atoms bond once, and that’s it. They’re just like that. Pretty quickly all the hydrogen atoms will collide and pair off into molecules. They will keep hitting each other, but they'll just bounce off. Scientists like to have a shorthand way of writing this molecule thingi. Here’s one way to show it, with the hydrogen symbols joined by a stick to show the chemical bond between the atoms. Another way is to write H2, with the little 2 after the H and a bit lower. A number written this way is called a subscript. What do you think the 2 stands for? It counts the number of hydrogen atoms in the molecule. Easy, heh! So when we have a balloon filled with hydrogen gas, it really contains trillions of trillions of H2 molecules. Let's do another thought experiment. We'll go back to our box filled with hydrogen atoms, but this time put an oxygen atom in there too. When a hydrogen atom crashes into an oxygen atom, they stick together. But wait, when another hydrogen atom hits, it also sticks to the oxygen. What about a third hydrogen atom? No, that’s if for oxygen. It can only make 2 bonds and then it’s done.

What is a Coordinate Covalent Bond?
 
04:40
This chemistry video tutorial provides a basic introduction into coordinate covalent bond. Line any covalent bond, electrons are shared. However, in a coordinate covalent bond, one atom donates both electrons that contribute to the formation of the bond. A lewis acid lewis base reaction can form a coordinate covalent bond as well as metal ligand interactions.

How Do Atoms Bond - Part 2 | Chemistry for All | FuseSchool
 
05:51
Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains almost all the atom’s mass, surrounded by shells of negatively charged electrons. Each shell is able to hold only up to a fixed number of electrons when it is said to be full. Hydrogen has a single positive charge in the nucleus and a single electron. If two hydrogen atoms approach each other, there is an attraction: the positive charge and the negative electron charge attract. However the first shell, for all atoms, can only contain two electrons so once the two Hydrogen atoms come together the two electrons essentially ‘fill’ the outer shell of both Hydrogen atoms. The atoms are essentially ‘glued’ together by the attraction of the two electrons and the two nuclei. The same form of electron share bonding occurs between any non-metallic elements, with the outer shell quickly becoming full, limiting the number of bonds that form. When there are four electrons in the outer shell, such as with carbon and silicon there is room for four more electrons so 4 bonds form. In this case it is possible to build up a 3-D structure with the bonding going on forever. In this way we see that carbon and silicon, as elements, have atoms chemically bonded into a 3D lattice so they are both solids at room temperature and very difficult to melt and vaporise. They are giant covalent structures. Metallic bonding is the way all metals and alloys are bonded, and explains the typical properties of metals. Atoms can be added as much as you want and there will never be enough electrons to fill the outer shell. So in metallic bonding, the atoms form a closely packed lattice where the atoms are not bonded by fixed pairs of electrons, but rather by a ‘sea’ of electrons roaming these partially filled outer shells at will. When two different atoms approach each other, covalent bonds can form. The number of electrons that are shared depends upon how many electrons are missing from the outer shells of the atoms. Overall, in this video you will learn how two atoms which approach each other have the possibility to bond if there is space in their outer electron shells. Non-metallic elements will tend to form self contained small molecules giving rise to volatile solids, liquids and all gases. Carbon and silicon will give rise to giant structures. Metallic elements will bond together to form metallic structures with loose electrons. When metal bonds with a non-metal ionic compounds are formed.

In order to write formulas for polyatomic ions, you have to look at a chart or table of polyatomic ions to find out what the charge of each one is. Then, you figure out how many other ions will be necessary to balance out the charges and make it neutral.

NH4Cl Bond Types (Ionic, Covalent, and Coordinate Covalent)
 
03:06
In this video we'll look at the three types of chemical bonds found in NH4Cl, Ammonium chloride. The overall compound is considered ionic because of the NH4+ and Cl- ions being electrostatically attracted. Within the NH4+ ion there are covlalent bonds, one of which is a coordinate covalent (sometimes called dative) bond. We can see the ionic bond clearly by looking at the Lewis struture for NH4Cl. The brackets are included in the structure to show that the ammonium and chloride ions are not sharing valence electrons, rather an electron was transferred.

Atom as a small particle present in every substance. Atoms are electrically neutral while ions carry charged due to loss or gain of electrons. Molecules are formed when two or more elements of the same atom combine while a compound is formed when two or more elements of different atoms combine. It also important to differentiate between ionic and Covalent Compounds. Basically, covalent compounds contains non-essential while ionic Compounds contains metals and non-metals. But there exception in the case of Ammonium chloride which contains non-metals but is still ionic. This is simply because we have two aggregate ions which is positively charged Ammonium and negatively charged Chlorine.

Ionic and covalent bonding animation
 
01:58
Ionic bonding formed when one atom has sufficient strength of attraction to remove ion from the other atom. Covalent bonding occurs when neither atom has sufficient strength to remove the other atom's electron. They would instead share electrons to form stable configurations of electrons.

VSEPR Theory: Introduction
 
20:30
To see all my Chemistry videos, check out http://socratic.org/chemistry This is an introduction to the basics of VSEPR Theory. VSEPR theory is a set of rules for how to look at a Lewis structure and determine the three dimensional (3D) shape of a molecule. The shapes have to do with the location of bonds and lone electrons pairs. In this video, we'll look at the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal

Polar Molecules Tutorial: How to determine polarity in a molecule
 
10:36
This video looks at how to determine polarity in a molecule by understanding how the bond polarities, molecule shape, and outside atoms influence polarity using bond polarity vector addition. This includes a flow chart that guides you through the various decisions needed to determine if a molecule is polar or not. Wikipedia 1/1/2018: In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other. While the molecules can be described as "polar covalent", "nonpolar covalent", or "ionic", this is often a relative term, with one molecule simply being more polar or more nonpolar than another. However, the following properties are typical of such molecules. A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital. Polar molecules[edit] The water molecule is made up of oxygen and hydrogen, with respective electronegativities of 3.44 and 2.20. The dipoles from each of the two bonds (red arrows) add together to make the overall molecule polar. A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. Other examples include sugars (like sucrose), which have many polar oxygen–hydrogen (−OH) groups and are overall highly polar. If the bond dipole moments of the molecule do not cancel, the molecule is polar. For example, the water molecule (H2O) contains two polar O−H bonds in a bent (nonlinear) geometry. The bond dipole moments do not cancel, so that the molecule forms a molecular dipole with its negative pole at the oxygen and its positive pole midway between the two hydrogen atoms. In the figure each bond joins the central O atom with a negative charge (red) to an H atom with a positive charge (blue). The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds – in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH3, molecule the three N−H bonds have only a slight polarity (toward the more electronegative nitrogen atom). The molecule has two lone electrons in an orbital, that points towards the fourth apex of the approximate tetrahedron, (VSEPR). This orbital is not participating in covalent bonding; it is electron-rich, which results in a powerful dipole across the whole ammonia molecule. Resonance Lewis structures of the ozone molecule In ozone (O3) molecules, the two O−O bonds are nonpolar (there is no electronegativity difference between atoms of the same element). However, the distribution of other electrons is uneven – since the central atom has to share electrons with two other atoms, but each of the outer atoms has to share electrons with only one other atom, the central atom is more deprived of electrons than the others (the central atom has a formal charge of +1, while the outer atoms each have a formal charge of −​1⁄2). Since the molecule has a bent geometry, the result is a dipole across the whole ozone molecule. When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond. For example, water forms H-bonds and has a molar mass M = 18 and a boiling point of +100 °C, compared to nonpolar methane with M = 16 and a boiling point of –161 °C. Nonpolar molecules[edit] A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Not every molecule with polar bonds is a polar molecule. Carbon dioxide (CO2) has two polar C=O bonds, but the geometry of CO2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.

Ionic Bonding Introduction
 
07:20
To see all my Chemistry videos, check out http://socratic.org/chemistry This video is an introduction to ionic bonding, which is one type of chemical bonding. Ionic bonds hold together metal and nonmetal atoms. In ionic bonding, electrons are transferred from a metal atom to a nonmetal atom, creating ions. These ions have opposite charge, so they stick together. Creative Commons Attribution-NonCommercial CC BY-NC
