The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The top and bottom oxygen molecule each have an unpaired electron which is available to join in a bond with sulfur. hydrated sulfate clusters using an empirical potential with bond lengths and bond angles held rigid. The sulfate(IV) ion/sulphate(IV) ion, SO 3 2-(sulfite ion/sulphite ion) is a trigonal pyramid shape, O-S-O bond angle ~109 o due to three groups of bonding electrons and one lone pair of electrons. Tetrahedral-- SP3 hybridized, like methane, CH4, with the hydrogen atoms arrayed around the carbon atom at 109.5° bond angles in three dimensions; Many shapes exist beyond tetrahedrals, but we are concentrating on that shape here. Name the type of bond formed in this reaction. You may think of it as a superposition of resonance structures with all possible combinations of $\ce{S=O}$ and $\ce{S-O-}$.
