A Medley of Potpourri: Silicon (updated)

A silicon atom has fourteen electrons.In the ground state, they are arranged in the electron configuration [Ne]3s 2 3p 2.Of these, four are valence electrons, occupying the 3s orbital and two of the 3p orbitals.Like the other meers of its group, the lighter carbon and the heavier germanium, tin, and lead, it has the same nuer of valence electrons as valence orbitals: hence, it can complete
