CORRELATION OFTHE COMPARATIVE REACTIVITY INERTNESS OF GOLDAND SILVER INTERMS OF SOME GLOBALTHEORETICAL DESCRIPTORS OF CHEMICAL REACTIVITYAND STABILITY

Abstract

In this communication we have correlated the chemical fact demonstrated that gold is more inert
 than silver in terms of some theoretical reactivity descriptors like absolute radius, ionization energy, global
 hardness and electrophilicity index. The chemical inertness of Au is attributed to its smaller absolute radius,
 higher ionization energy, greater hardness value and larger electrophilicity index coupled with relativistic
 effect compared to that of Ag. Thus our observation is a theoretical rationale of the existing and old view, on
 the basis of chemical observation, that Au is more inert than Ag.
