Intro

Intro to polarisability and covalent character in ionic compounds

How polarisability and electronegativity affect covalent character

How ionic bonds gain covalent character through polarisation

An A-level chemistry guide to polarisability: what it means for an ion's electron cloud to be distorted, the difference between polarising power and polarisability, Fajans' rules, periodic trends, and how this explains deviations from purely ionic bonding.
