Webbför 2 dagar sedan · The shape of a molecule or ion is governed by the arrangement of the electron pairs around the central atom. All you need to do is to work out how many electron pairs there are at the bonding level, and then arrange them to produce the minimum amount of repulsion between them. You have to include both bonding pairs and lone pairs. http://www.alevelchem.com/aqa_a_level_chemistry/unit3.5/s354/02.htm
