Covalent Bonding. Noble gases have complete outer electron shells, which make them stable. The coming together and sharing of electron pairs leads to the formation of a chemical bond known as a covalent bond. Two chlorine atoms come together and share their electrons to form a molecule of chlorine. In this way, each atom will have eight electrons in its valence shell. As a single pair of electrons is shared between them, the bond is known as a single covalent bond. A single covalent bond is represented by a single dash between the atoms. When two oxygen atoms come together, they each share 2 electrons to complete their octets. Since they share two pairs of electrons, there is a double bond between the oxygen atoms. Similarly, Nitrogen atoms share a triple covalent bond to form a molecule of Nitrogen.

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?

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

To see all my Chemistry videos, check out http://socratic.org/chemistry Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

052 - Bond Length and Bond Energy In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond energy increases and the bond length decreases. Increasing numbers of bonds will also increase the energy and decrease the length. Do you speak another language?

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. We show five examples of covalent bonds using Lewis dot structure notation: HF, CO2, H2, H2O and CCl4.

In this video I explain the neurological and chemical process that cause you to bond with an abusive and toxic partner. Those who have never been in an abusive relationship struggle to understand how people remain in one for so long. If somebody was mistreating you, "why did you stick around?" they ask. For survivors, this can be a really tough question to answer. The lucky ones escape, and stumble upon articles or books that give them the terms to be able to understand what happened to them, and thus describe their experience. Other times, though, this doesn't happen, and people might not even be aware they were in a relationship that could be classed as "abusive." This is because we are conditioned to believe abuse is always physical. On TV and in films, we see characters who are obviously evil. They are violent to their partners, shout at them aggressively, or even murder them in a fit of rage. While this does happen, it's not a true representation of the abuse many others experience. ——Brand new ebook ——— How To Get Closure From A Toxic Relationship My first NEW ebook looking at the concept of closure and why it is so painful when you don't receive it (especially in the ending of a narcissistic relationship) .

How do you name them, is polarity there? It's a chemical bond, baby, A chemical bond, baby. [RAP VERSE 1] - Eric Okay first off we'll start with ionic. They deal with ions, isn't that ironic, Cations, anions, polyatomic, Make a strong bond, like a bomb that's atomic, Typically a metal and a nonmetal bond, To get an octet so that they become strong, They get together and transfer electrons, They share them equally, neither one is conned. [SINGING VERSE 1] -Stephen What makes the bonds stronger? And last longer? And have a higher melting point you think? A correct inference, would be the difference, In electronegativity. To name it put the cation first you see, And on the anion put I D E Unless it's polyatomic then let it be Be...be...be... [CHORUS] -Stephen [RAP VERSE 2] -Eric Im'a talk about covalent bonds now Two nonmetals bond, you wanna know how? Atoms come together, cause they want an octet They share electrons to get eight in their set. Covalent differs from ionic greatly: They have a smaller difference in e-negativity, Percent ionic character is less obviously, What, about polarity? [SINGING VERSE 2] -John Non-polar, beats polar, When it comes to sharing equally. But polar, has a higher, Melting point than non-polar's be. Naming them is easy thankfully, Just put a prefix on the atom please, Rappin' bout bonds, yeah I'm a G. G...G...G [CHORUS] -- Stephen [BRIDGE] Now metallic bonds, are the bond type number three. Electrons aren't stagnant, they move around in a sea. It's senior year with Standish, and I'm lucky with a "C," Can't wait to get out of here, it's AP Chemistry. [CHORUS]

Check us out at http://chemistry.tutorvista.com/inorganic-chemistry/atomic-structure.html Atomic Structure To review, an atom consists of a small, dense nucleus containing all of its protons and neutrons, surrounded by electrons that fill the remaining volume of the atom. The atom stays electrically neutral because the number of protons and electrons are usually equal. In this section, the structure of atoms and the chemical properties will be studied, and the number of electrons and the way they are distributed generally determine them. Chemical Bonding: Introduction Atoms of almost every element has the ability to combine with other atoms to form more complex structures. The forces of attraction that bind them together are chemical bonds. To understand chemistry, the nature and origin of chemical bonds is important, since the basis of chemical reactions is the forming and the breaking of bonds and the changes in bonding forces. There are two main classes of bonding forces: covalent bonds and ionic bonds. Covalent bonding deals with the sharing of electrons between atoms. Ionic bonding deals with the transfer of electrons between atoms. Please like our facebook page http://www.facebook.com/tutorvista Follow us at: https://plus.google.com/+tutorvista/

Subscribe to watch more online chemistry courses & science videos: http://www.youtube.com/channel/UCiX8pAYWBppIbtUZTfGnRJw?sub_confirmation=1 About Atomic School: Atomic School supports the teaching of Atomic Theory to primary school & science students . 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.

Scientists have used an X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory to get the first glimpse of the transition state where two atoms begin to form a weak bond on the way to becoming a molecule. This fundamental advance, reported Feb. 12 in Science Express and long thought impossible, will have a profound impact on the understanding of how chemical reactions take place and on efforts to design reactions that generate energy, create new products and fertilize crops more efficiently. “This is the very core of all chemistry. It’s what we consider a Holy Grail, because it controls chemical reactivity,” said Anders Nilsson, a professor at the SLAC/Stanford SUNCAT Center for Interface Science and Catalysis and at Stockholm University who led the research. “But because so few molecules inhabit this transition state at any given moment, no one thought we’d ever be able to see it.”
