Ionic
Bonding
Ionic bonding in AQA 3.1.3 focuses on electrostatic attraction between oppositely charged ions in a lattice, the prediction of ion charges and the construction of formulae for ionic compounds. These pages also connect ionic bonding to lattice structure and the physical properties of ionic substances.
Revision Notes
4 revision notes, in the order the specification teaches them.
