10 chaptersAtomic Structure
Use particles, orbitals and ionisation data to explain the behaviour of atoms and ions.
3 topicsChemical Bonding
Explain particles, molecular shape and material properties through electrostatic attraction.
3 topicsTheories of Acids and Bases
Follow protons, calculate strong-solution pH and explain how buffers respond to change.
3 topicsThe Periodic Table
Use electron arrangements and structure to explain trends, reactions and unknown elements.
3 topicsThe Mole Concept and Stoichiometry
Turn mass, gas and solution evidence into amounts, formulae and balanced chemical relationships.
3 topicsChemical Energetics: Thermochemistry
Read reaction energy, measure heat and use supplied cycles without losing signs or stoichiometric factors.
3 topicsReaction Kinetics
Infer a rate law from evidence and explain how concentration, temperature and catalysts change reaction speed.
3 topicsChemical Equilibria
Explain a changing equilibrium, calculate its composition and connect the Haber process to rate and yield.
3 topicsPolymers and Organic Chemistry
Read organic structures, predict reactions and explain why a protein or plastic behaves as it does.
12 topicsData and Experimental Skills
Read unfamiliar evidence, make useful measurements and explain what a result can support.
