Chemical reactions & Metals

This resource provides a comprehensive overview of redox reactions and the chemistry of metals, aligned with key curriculum objectives. It introduces oxidation and reduction in terms of oxygen transfer, electron movement, and changes in oxidation state, helping students build a deep conceptual understanding of redox processes. The lesson explores the physical and chemical properties of metals, including their reactions with water, steam, and acids, as well as their position in the reactivity series. Students are guided through displacement reactions, corrosion (rusting), and methods of preventing corrosion such as galvanising and sacrificial protection. Further, the resource covers the extraction of metals from ores, linking methods such as reduction with carbon and electrolysis to the metal’s position in the reactivity series. It also includes the study of alloys, their structure, and why they are often stronger than pure metals. With a wide range of structured explanations, exam-style questions, and application tasks, this resource is ideal for reinforcing understanding, developing analytical skills, and preparing students for assessments in chemistry.
