Valence bond theory — In chemistry, valence bond theory explains the nature of a chemical bond in a molecule in terms of atomic valencies. [Murrel, JN, Kettle, SF Tedder, JM The Chemical Bond , John Wiley Sons (1985) ISBN 0 471 90759 6] Valence bond theory summarizes… … Wikipedia
Modern valence bond theory — is the term used to describe applications of valence bond theory with computer programs that are competitive in accuracy and economy with programs for the Hartree Fock method and other molecular orbital based methods. The latter methods dominated … Wikipedia
Bond valence method — The bond valence method (or bond valence sum) (not to be mistaken for the valence bond theory in quantum chemistry) is a popular method in coordination chemistry to estimate the oxidation states of atoms.The basic idea is that the valence V of an … Wikipedia
Valence (chemistry) — For other uses, see Valence (disambiguation). In chemistry, valence, also known as valency or valence number, is a measure of the number of bonds formed by an atom of a given element. Valence can be defined as the number of valence bonds[1] a… … Wikipedia
Chemical bond — A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges, either between electrons and… … Wikipedia
