2 BASIC IDEAS Shapes of molecules and ions depends on total number of electron pairs around the central atom. Two types of electron pairs: Bonding pairs (i.e. e-’s in a covalent bond) Non-bonding pairs (i.e. lone pairs) These electron pairs repel as far as possible (but lone pairs repel more than bonding pairs).
