This course provides comprehensive coverage of all topics for Paper 1 of the AQA GCSE Chemistry specification (8462). It is designed to help you master the fundamental principles of chemistry, from atomic structure to energy changes, and build the secure knowledge needed to achieve a high grade. The course is optimised for audio learning, focusing on clear explanations, precise scientific language, and active recall of key facts, definitions, and processes. You will learn the concepts, practice the calculations, and understand the required practicals in detail. To succeed, you must also complete practice exam questions and review diagrams outside of this audio course, especially for topics like drawing atomic structures, reaction profiles, and interpreting graphs.

Covers the modern nuclear model of the atom, the properties of protons, neutrons, and electrons, and how to determine their numbers in atoms and ions. Also covers isotopes, relative atomic mass, and electronic structure.

Covers the arrangement of the periodic table by atomic number, the work of Mendeleev, and the location of metals and non-metals. Explains how an element's position relates to its electronic structure.

Covers the properties and trends in reactivity for Group 1 (Alkali Metals), Group 7 (Halogens), and Group 0 (Noble Gases), linking these properties to their electronic structures.

This deck covers the typical properties of transition metals, such as high density, high melting points, and low reactivity. It focuses on their special characteristics, including their roles as catalysts, their ability to form ions with different charges, and their formation of coloured compounds, comparing them throughout with Group 1 metals.

Covers the three main types of chemical bonding: ionic (transfer of electrons), covalent (sharing of electrons), and metallic (delocalised electrons). Includes understanding representations like dot and cross diagrams.

Explains how the type of bonding and structure determines the physical properties (melting point, boiling point, conductivity) of a substance. Covers ionic compounds, small molecules, polymers, giant covalent structures, and metals/alloys.

Covers the structure and properties of diamond, graphite, graphene, and fullerenes. Also introduces nanoparticles, their properties based on a high surface area to volume ratio, and their uses and risks.

Covers the law of conservation of mass, balancing simple symbol equations, and calculating relative formula mass (Mr). Explains apparent mass changes in non-enclosed systems involving gases.

Introduces the mole as a unit for the amount of substance. Covers calculations using mass, Mr, and moles. Explains how to use moles to balance equations and determine the limiting reactant in a reaction.

Covers how to calculate the concentration of a solution in grams per decimetre cubed. Introduces and explains how to calculate percentage yield and atom economy for a chemical reaction.

Covers calculating concentration in moles per decimetre cubed and converting between mol/dm³ and g/dm³. Also covers calculations involving the volume of gases, using the molar gas volume.

Covers the reactivity series of metals, including their reactions with acid and water. Explains displacement reactions and the extraction of metals. Defines oxidation and reduction in terms of both oxygen and electrons (OILRIG).

Covers the reactions of acids with metals, metal oxides, metal hydroxides, and metal carbonates to produce salts. Includes the pH scale, neutralisation, and the definition of strong and weak acids in terms of ionisation for Higher Tier students.

Explains the process of electrolysis, including key terms. Covers the prediction of products from the electrolysis of molten ionic compounds and aqueous solutions. Includes writing half equations for reactions at the electrodes (Higher Tier).

Defines exothermic and endothermic reactions. Covers the interpretation of reaction profiles, including activation energy. Includes calculating overall energy change from bond energies (Higher Tier).

Explains how a simple chemical cell is made and how voltage depends on the metals used. Covers the operation of a hydrogen fuel cell, including the reactions at the electrodes and its advantages and disadvantages.

Covers the method for preparing a pure, dry sample of a soluble salt from an insoluble base or carbonate. Includes the reasons for each step, such as using an excess of the base, filtration, and crystallisation.

Learn the method for the required practical on titration. This deck covers the correct use of a pipette and burette, the role of indicators, how to obtain accurate and reliable results, and the calculations needed to determine the concentration of a solution.

Covers the method for investigating the products of electrolysing different aqueous solutions using inert electrodes. Includes how to set up the apparatus, collect and test any gases produced, and observe changes.

Covers the method for investigating variables that affect temperature changes in reacting solutions, such as neutralisation. Includes how to measure temperature change accurately and reduce heat loss.
