The isolability concept utilized to explain cluster chemistry may simply be regarded as being synonymous to valence. By assigning a valence to organometallic fragments, many structures of organometaalic compounds can readily be explained. The valence of a fragment is deduced from the octet rule or the 18 electron rule. This paper briefly reflects and reviews the isolability concept and points out the its direct linkage to the valence concept. This approach will greatly improve and simplify the teaching of molecular cluster systems at both undergraduate and postgraduate levels. Ample examples of molecules to illustrate the application of valence concept to explain molecular geometry are given.
