Start with the Lewis structure or with the AX E designation. X = attached atoms, E = lone pairs on central atom A. 2. Find the sum of the number of bonded atoms plus the number of lone pairs. (This is n + m .) 3. Select the correct arrangement. 4. Enter the atom positions into the arrangement and determine the correct shape. VSEPR Follow-up With respect to deviations from ideal bond angles and to molecular polarity, three categories can be
