What makes a metal reactive?
When a metal reacts, its atoms lose electrons and form positive ions. A metal is more reactive when its atoms lose electrons and form positive ions more readily.
Step-by-step lessons covering AQA GCSE Chemistry 4.1.2 The reactivity series 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.
