Key Concepts in Chemistry
Atomic Structure and the Periodic Table
A GCSE chemistry revision page on atomic structure covering subatomic particles, electronic structure and shells, isotopes, relative mass/calculations, how to draw atom diagrams, and the development of atomic models with examples and explanations.
Ionic Bonding
A GCSE chemistry revision page on ionic bonding explaining how ions form from atoms, how oppositely-charged ions attract to form ionic compounds, drawing dot-cross diagrams, lattice structures, and the typical properties of ionic substances.
Covalent Bonding
GCSE revision page on covalent bonding covering what covalent bonds and molecules are, drawing dot-and-cross diagrams using valency, simple molecular properties (melting/boiling, conductivity), giant covalent structures, diamond vs graphite, and graphene/fullerenes/nanotubes.
Types of Substance - Ionic, Covalent or Metallic?
A GCSE chemistry revision page on types of substance, explaining the properties of metals and non-metals, what polymers are, models of substances (2D/3D/dot-cross/ball-and-stick), identifying bonding types from data and practical tests for bonding types.
Calculations involving Masses
A GCSE chemistry revision page on calculations, covering relative formula mass, empirical formula, conservation of mass, concentration, moles, Avogadro’s constant, limiting reactants, and stoichiometric working with examples and step-by-step explanations.
Paper One
STATES OF MATTER AND SEPARATION TECHNIQUES
GCSE revision on states of matter and separation techniques: particle arrangement in solids/liquids/gases, state changes and heating graphs, pure substances vs mixtures, filtration and crystallisation, paper chromatography and Rf, simple and fractional distillation, and the inks core practical.
ACIDS, BASES AND NEUTRALISATION
A GCSE Chemistry revision page on acids, bases and indicators explaining key ideas such as pH, acid and alkali ions, indicator colour changes, dilute vs concentrated definitions, reactions with metals/carbonates, tests for gases, and neutralisation ionic equations.
CHEMICAL CHANGE PRACTICALS
A GCSE chemistry revision page showing core chemical change practicals, including making salts from insoluble or soluble reactants and investigating pH changes with practical steps, key observations, and variables for experiments.
ELECTROLYSIS
This page is an Edexcel GCSE revision page explaining electrolysis, including definitions of electrolytes and electrolysis, ion movement at electrodes, making pure copper, the electrolysis core practical with variables and risks, predicting products, and writing half-equations.
METALS AND EQUILIBRIA
A GCSE revision page explaining metals and equilibria including reactivity of metals, extraction, displacement reactions, and dynamic equilibrium concepts with practical examples and explanations of how systems respond to changes.
PAPER ONE: SEPARATE CHEMISTRY
A GCSE revision page covering all of the separate chemistry content for Paper 1 topics transition metals, corrosion vs rusting, electroplating, concentration & titration calculations, yields & atom economy, dynamic equilibrium, fertilisers, chemical cells and fuel cells with practical examples.
Paper Two
GROUPS IN THE PERIODIC TABLE
A GCSE chemistry revision page on groups in the periodic table covering the alkali metals’ properties and reactivity trends, noble gas inertness and uses, halogen states and reactivity patterns, reactions with metals, and displacement trends down group 7.
RATES AND ENERGY CHANGES
A GCSE revision page on rates of reaction and energy changes including practical methods for measuring rate, collision theory, factors affecting rate, interpreting rate graphs, catalysts, activation energy, reaction profiles, and calculations of rate and energy change.
HYDROCARBONS AND COMBUSTION
A GCSE chemistry revision page on hydrocarbons covering alkanes and alkenes, combustion reactions, cracking to produce smaller alkanes and alkenes, and how these reactions relate to fuel properties and chemical behaviour with examples and explanations.
THE CHANGING ATMOSPHERE
A GCSE chemistry revision page on the Earth’s atmosphere, explaining composition and changes over time, greenhouse gases and global warming, formation of pollutants from combustion, carbon footprint ideas, and methods to reduce gas emissions.
SEPARATE CHEMISTRY: IONS AND MATERIALS
GCSE revision page on ions and materials covering flame tests, hydroxide precipitates, tests for ammonium, carbonates, sulfates and halides, an ions core practical, instrumental analysis (flame photometry), plus nanoparticles, ceramics, composites and choosing materials based on properties.
SEPARATE CHEMISTRY: ORGANIC CHEMISTRY
