A quantitative definition of hypervalency.

ABSTRACT: From the inception of Lewis' theory of chemical bonding, hypervalency has remained a point of difficulty that has not been fully resolved by the currently accepted qualitative definition of this term. Therefore, in this work, a quantitative measure of hypervalency has been developed. The only required input is the atomic charge map, which can be obtained from either quantum calculations or from experiment. Using this definition, it is found that well-known species such as O₃, CH₂N₂ and ClO₄^-, are indeed hypervalent, whilst others such as XeF₄, PCl₅ and SO₄^2-, are not. Quantitative analysis of known species of general formulae XF _n^m-, XCl _n
