Ah, sheri, for molecules with lone pairs, you must count both bonds and lone pairs around the central atom for the steric number, *then* imagine the electron pairs pushing to arrange themselves as far apart as possible—that shape is the electron geometry. The molecular shape is what you *see*, after you hide the lone pairs and look only at the atoms. For example, SF4’s steric number is 5, so its electron geometry is trigonal bipyramidal, but with one lone pair, it becomes a see-saw shape. It’s like judging the true shape of my neem tree outside the shop; you must see past the missing branch on one side to understand why it leans the way it does.
