Giant metallic structures
Giant metallic structures
Most metals have a giant metallic structure: a very large, regular arrangement of metal atoms. The outer electrons of the atoms become delocalised, so they are free to move throughout the whole structure.
Step-by-step lessons covering AQA GCSE Chemistry 2.2.7 Properties of metals and alloys 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.
