Chemistry

AQA GCSE Chemistry (separate science, Higher tier), topics C1 to C10.

Terminology: every key term, with pictures

Topics

C1

Atomic Structure and the Periodic Table

What atoms are made of, how our model of the atom developed, and how the periodic table groups elements with similar properties.

C2

Bonding, Structure and Properties of Matter

How atoms join by ionic, covalent and metallic bonds, and how a substance's structure explains its properties.

C3

Quantitative Chemistry

Using relative masses, moles and concentrations to work out how much of each substance reacts and is made.

C4

Chemical Changes

How metals and acids react, how salts are made, and how electrolysis splits compounds using electricity.

C5

Energy Changes

Why some reactions give out heat and others take it in, and how cells and fuel cells turn chemical energy into electricity.

C6

The Rate and Extent of Chemical Change

What makes reactions faster or slower, and how reversible reactions reach equilibrium.

C7

Organic Chemistry

How crude oil gives us fuels and plastics, and how alkenes, alcohols, acids and polymers react.

C8

Chemical Analysis

How chemists test whether a substance is pure and identify gases and ions in an unknown sample.

C9

Chemistry of the Atmosphere

How Earth's atmosphere formed and changed, and how human activity adds greenhouse gases and pollutants to it.

C10

Using Resources

How we make water safe, extract and protect metals, judge a product's environmental impact and make ammonia for fertilisers.
