Shapes of simple molecule and ions

Bonding pairs and lone (non-bonding) pairs of electrons as charge clouds that repel each other. Pairs of electrons in the outer shell of atoms arrange themselves as far apart as possible to minimise repulsion: VSEPR (valence shell electron pair repulsion) The effect of electron pair repulsion influences bond angles Students should be able to: • explain the shapes of, and bond angles
