Summary of VSEPR: (4)

Molecule geometry depends on electron pairs in the outer shell of teh central atom 1 multiple bond = 1 electron domain electron pairs (electron domains) in the valence shell of an atom repel each other and will therefore take up positions in space to minimise these repulsions = as far away from each other as possible Lone pairs affect the shape but can't be seen they repel bonding pairs of electrons more than the bonding pairs as they are closer to the bonding electrons
