14 chaptersAtomic Structure
Count particles, build electron configurations and read the evidence in ionisation energies.
4 topicsChemical Bonding
Use electrons, molecular shape and electrostatic attraction to explain structures, properties and reactivity.
6 topicsThe Gaseous State
Know when the ideal-gas model works, calculate gas quantities and separate the pressures in a mixture.
3 topicsTheories of Acids and Bases
Choose the definition that explains the reaction: aqueous ions, proton transfer or electron-pair donation.
3 topicsThe Periodic Table
Explain trends from electrons and structure, then predict the oxides, chlorides and redox behaviour of unfamiliar elements.
6 topicsThe Mole Concept and Stoichiometry
Turn masses, gas volumes and solution measurements into amounts, then let a balanced equation connect them.
5 topicsChemical Energetics
Track energy through bonds and cycles, then combine enthalpy and entropy to assess thermodynamic feasibility.
5 topicsReaction Kinetics
Extract a rate law from data, test a mechanism, and explain how conditions and catalysts change reaction speed.
5 topicsChemical Equilibria
Explain a changing equilibrium through competing rates, then calculate composition and justify industrial choices.
4 topicsChemistry of Aqueous Solutions
Calculate acidity, follow titrations and buffers, and predict whether an ionic solid dissolves or precipitates.
6 topicsOrganic Chemistry
Read structures, reason through electron movement, and connect functional groups with the conditions that transform them.
34 topicsElectrochemistry
Measure and combine electrode potentials, predict cell reactions, and calculate what electrolysis produces.
7 topicsTransition Elements
Connect d-electron configurations to physical trends, variable oxidation states, coloured complexes and catalysis.
6 topicsData and Experimental Skills
Read unfamiliar evidence, make useful measurements and explain what a result can support.
