"Webare collectively described as either the Polyhedral Skeletal Electron Pair Theory (ref. 19) or Wade's Rules. The ideas have proved to be surprisingly useful for analysing the structures of a wide range of polyhedral molecules, however by their very simplicity there are a number of notable exceptions to the theory. These exceptions can be " - Polyhedral skeletal electron pair theory
