GCSE Chemistry
Chemistry Topics
GCSE Chemistry topic pages will be added here. Start with the main areas: atomic structure, bonding, quantitative chemistry, chemical changes, energy changes, rates, organic chemistry, analysis and the atmosphere.
Atomic Structure
Atoms, elements, compounds, mixtures, isotopes, electronic structure and the periodic table.
Bonding and Structure
Ionic, covalent and metallic bonding, simple molecules, polymers, giant structures and nanoparticles.
Quantitative Chemistry
Relative formula mass, moles, equations, concentration, gas volumes and percentage yield.
Chemical Changes
Reactivity, acids, alkalis, salts, electrolysis, oxidation and reduction.
Energy Changes
Exothermic and endothermic reactions, reaction profiles, bond energy and cells.
Rates and Equilibrium
Collision theory, catalysts, reversible reactions, dynamic equilibrium and Le Chatelier's principle.
Organic Chemistry
Crude oil, hydrocarbons, alkanes, alkenes, cracking, alcohols, carboxylic acids and polymers.
Chemical Analysis
Pure substances, chromatography, gas tests, ion tests, flame tests and instrumental methods.
Chemistry of the Atmosphere
Early atmosphere, greenhouse gases, climate change, pollutants and carbon footprint.
Using Resources
Finite resources, potable water, life cycle assessments, recycling, corrosion and alloys.
