WebSep 7, 2024 · How do you determine the molecular shape of a molecule? September 7, 2024 by Alexander Johnson. The repulsion between valence electron pairs in the outer shell of the central atom determines the shape of the molecule. You must determine the steric number (SN) — the number of bonding pairs and lone pairs about the central atom. http://intro.chem.okstate.edu/1314F00/Lecture/Chapter10/VSEPR.html
