#20 - The Uses of Metals
Edexcel IGCSE Chemistry - The Companion Audio Guide
Understand the uses and extraction of metals. Most metals are extracted from ores, with less reactive metals extracted using carbon reduction and more reactive ones via electrolysis. Metals like aluminium, copper, and iron are used widely due to their properties, such as conductivity and malleability. Alloys, mixtures of metals, are stronger and more resistant than pure metals.
