Step 3. Draw single bonds to the central atom and subtract 2e – for each bond:
Four single bonds use 8 e – , so 32 e – – 8 e – = 24 e – remaining.
Step 4. Distribute the remaining valence electrons in pairs, beginning with the surrounding atoms, so that each atom has an octet:
Molecules with More than One Central Atom
