31Outer sphere electron transfer — Outer sphere refers to an electron transfer (ET) event that occurs between chemical species that remain separate intact before, during, and after the ET event.[1] In contrast, for inner sphere electron transfer the participating redox sites… …
32Carbon-oxygen bond — A carbon oxygen bond is a covalent bond between carbon and oxygen and one of the most abundant in organic chemistry and biochemistry. [ Organic Chemistry John McMurry 2nd Ed.] Oxygen has 6 valence electrons and prefers to share two electrons in… …
33metallic bond — Chem. the type of chemical bond between atoms in a metallic element, formed by the valence electrons moving freely through the metal lattice. * * * ▪ chemistry force that holds atoms together in a metallic substance (metal). Such a solid… …
34Dangling bond — In chemistry, a dangling bond is an unsatisfied valence on an immobilised atom. In order to gain enough electrons to fill their valence shells (see also octet rule), many atoms will form covalent bonds with other atoms. In the simplest case, that …
35Shared pair — In chemistry, a shared pair is a pair of electrons bonding two atoms together by being shared by the two atoms, because the positive nuclei are attracted to the negative electrons.ee also*Covalent bond *Diatomic molecule …
36chemical bonding — ▪ chemistry Introduction any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another …
37History of the molecule — In chemistry, the history of the molecule traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms. The modern concept of molecules can be traced back towards pre scientific Greek philosophers… …
38Lewis, Gilbert N. — ▪ American chemist Introduction in full Gilbert Newton Lewis born Oct. 23, 1875, Weymouth, Mass., U.S. died March 23, 1946, Berkeley, Calif. American physical chemist best known for his contributions to chemical thermodynamics, the… …
