A more direct indication of the increased stability of the divalent state relative to the others derives from the patterns in the individual bond dissociation energies. Specifically, it is generally observed that the second BDE in an SiX4 compound is considerably smaller than the first. Walsh (99) was the first to point this out, and he has defined the difference between the first and second BDE to be the divalent state stabilization...
