Ionic Bonding
Ionic compounds form when electrons are transferred and oppositely charged ions attract each other in a giant ionic lattice.
The section also covers ionic and metallic bonding, simple molecular and giant lattices, and intermolecular forces with hydrogen bonding and the anomalous properties of water.
Revision Notes
3 revision notes, in the order the specification teaches them.
Nature of Ionic Bonding
Revise electron transfer, ion formation and the electrostatic attraction between oppositely charged ions in ionic compounds.

Polarisation of Ions
Learn how small highly charged cations can distort anion electron clouds, giving some ionic compounds partial covalent character.
Start revising
Physical Properties of Ionic Compounds
Connect giant ionic lattice structure with melting point, solubility, brittleness and electrical conductivity.
