Ionic Bonding – GCSE Chemistry Revision (AQA Additional Science – Double and Triple)


Why bond? Elements react with other elements because they ‘want’ to end up with a full outer electron shell Electrons surround the nucleus of an atom in shells – remember Atomic Structure. The shells go (2,8,8) when full Getting the … Continue reading
