Fascinating Fact:

Aluminium alloys are lighter than many other metals but can still be strong. They are used in vehicles and aircraft where mass matters.

In GCSE Chemistry, metals and alloys help you link structure to properties. You compare pure metals with alloys, explain why alloys are often harder, and connect properties like conductivity and malleability to real-world uses.

Key Terms

Alloy: A mixture of a metal with other elements, designed to improve properties such as strength or resistance to corrosion.
Malleable: Able to be hammered or rolled into shape without cracking.
Corrosion: The gradual breakdown of a metal caused by chemical reactions with substances in the environment, such as oxygen and water.

Frequently Asked Questions

Why are alloys harder than pure metals in GCSE Chemistry?

Alloys are harder because the different-sized atoms disrupt the regular layers in a pure metal. This makes it harder for the layers to slide over each other, so the material is stronger.

What are common properties of metals that GCSE students need to know?

Metals usually conduct electricity and heat, have high melting points, and are shiny when freshly cut. Many are also malleable and ductile, which makes them useful for wires and sheets.

What is the difference between a metal and an alloy?

A pure metal is one element, such as copper or aluminium. An alloy is a mixture, such as steel or brass, made to change properties like strength, hardness, or corrosion resistance.
