  1. VSEPR Valence Shell Electron Pair Repulsion Theory Determining the Shape of a Molecule

  2. VSEPR theory explains and predicts the geometry of molecules by counting pairs of electrons that repel each other to minimize repulsion. STEP 1 - Draw the Lewis structure for the molecule, including the electron pairs around the central atom. STEP 2 - Count the total number of bonding pairs (bonded atoms) and lone pairs of electrons around the central atom STEP 3 - Refer to reference table and use the number of pairs of electrons to predict the shape of the molecule
