01

Atomic Structure

Count particles, build electron configurations and read the evidence in ionisation energies.

4 topics

02

Chemical Bonding

Use electrons, molecular shape and electrostatic attraction to explain structures, properties and reactivity.

6 topics

03

The Gaseous State

Know when the ideal-gas model works, calculate gas quantities and separate the pressures in a mixture.

3 topics

04

Theories of Acids and Bases

Choose the definition that explains the reaction: aqueous ions, proton transfer or electron-pair donation.

3 topics

05

The Periodic Table

Explain trends from electrons and structure, then predict the oxides, chlorides and redox behaviour of unfamiliar elements.

6 topics

06

The Mole Concept and Stoichiometry

Turn masses, gas volumes and solution measurements into amounts, then let a balanced equation connect them.

5 topics

07

Chemical Energetics

Track energy through bonds and cycles, then combine enthalpy and entropy to assess thermodynamic feasibility.

5 topics

08

Reaction Kinetics

Extract a rate law from data, test a mechanism, and explain how conditions and catalysts change reaction speed.

5 topics

09

Chemical Equilibria

Explain a changing equilibrium through competing rates, then calculate composition and justify industrial choices.

4 topics

10

Chemistry of Aqueous Solutions

Calculate acidity, follow titrations and buffers, and predict whether an ionic solid dissolves or precipitates.

6 topics

11

Organic Chemistry

Read structures, reason through electron movement, and connect functional groups with the conditions that transform them.

34 topics

12

Electrochemistry

Measure and combine electrode potentials, predict cell reactions, and calculate what electrolysis produces.

7 topics

13

Transition Elements

Connect d-electron configurations to physical trends, variable oxidation states, coloured complexes and catalysis.

6 topics

14

Data and Experimental Skills

Read unfamiliar evidence, make useful measurements and explain what a result can support.
