Summary
The topic of metals in IGCSE Chemistry covers their properties, reactivity, extraction, and uses.
- Properties of metals — characteristics that define metals such as conductivity and malleability. Example: Metals like copper are good conductors of electricity.
- Reactivity series — a list of metals arranged in order of their reactivity. Example: Potassium is more reactive than iron.
- Extraction of metals — processes used to obtain metals from their ores. Example: Iron is extracted from its ore using a blast furnace.
- Uses of metals — various applications of metals based on their properties. Example: Aluminum is used in aircraft manufacturing due to its light weight.
