Giant ionic lattices
Giant ionic lattices

An ionic compound contains positive ions and negative ions with no overall electrical charge. The ions form a giant ionic lattice, which is a regular, repeating arrangement containing a very large number of ions.
Step-by-step lessons covering AQA GCSE Chemistry 2.2.3 Properties of ionic compounds for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
