Atomic structure and the periodic table
Atoms, elements and compounds - AQA
Chemists use symbols and formulae to represent elements and compounds. Word equations and balanced chemical equations represent the changes that happen in chemical reactions.
Mixtures - AQA
There are different ways to separate mixtures, such as filtration, crystallisation, simple distillation, fractional distillation and chromatography. The method chosen depends on the type of mixture.
Atomic structure - AQA
Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. The number of subatomic particles in an atom can be calculated from the atom's atomic number and mass number.
The periodic table - AQA
Mendeleev made an early periodic table. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic structures model how electrons are arranged in atoms.
Groups in the periodic table - AQA
Elements in the same group of the periodic table show trends in physical properties, such as boiling point. They have the same number of electrons in their outer shell, so they are similar in their chemical properties.
Transition metals - AQA
The transition elements are metals. They have high melting points and densities, and are strong and hard. They form coloured compounds and act as catalysts.
Sample exam questions - atomic structure and the periodic table - AQA
Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
Bonding, structure and the properties of matter
The three states of matter - AQA
The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state.
Ionic compounds - AQA
An ionic compound is made up of charged particles, called ions. It has a giant lattice structure with strong electrostatic forces of attraction.
Small molecules - AQA
A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have low melting and boiling points, and do not conduct electricity.
Giant covalent molecules - AQA
Giant covalent substances have many atoms joined together by covalent bonds. Diamond, graphite and graphene are forms of carbon with different giant covalent structures.
Metals and alloys - AQA
The structure of metals explains their high melting and boiling points and their conductivity. The properties of a metal can be modified by mixing it with another substance to form an alloy.
Nanoscience - AQA
Nanoparticles are 1 nm to 100 nm in size. They have very large surface area to volume ratios. The properties of nanoparticulate substances are different from those of the same substance in bulk.
Sample exam questions - bonding, structure and matter - AQA

Quantitative chemistry
Calculations in chemistry - AQA
Relative formula masses can be calculated and used in conservation of mass calculations. Calculations can be carried out to find out concentrations of solution and uncertainties in measurements.
Calculations in chemistry (Higher) - AQA
The mole is the unit for amount of substance. The number of particles in a substance can be found using the Avogadro constant. The mass of product depends upon the mass of limiting reactant.
Atom economy, percentage yield and gas calculations - AQA
Percentage yield and atom economy show how much desired product is obtained compared to amounts of starting materials. Gas calculations show volumes of gas used and obtained in chemical reactions.
Sample exam questions - quantitative chemistry - AQA
Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
Chemical changes
Reactions of metals - AQA
The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
Acids, alkalis and salts - AQA
Indicators are used to determine whether a solution is acidic or alkaline. Acids react with metals, bases and carbonates to produce salts. Neutralisation is the reaction between an acid and a base.
Titrations - AQA
The volumes of acids and alkali solutions that react with each other can be measured by titration using a suitable indicator.
Electrolysis - AQA
Electrolysis involves using electricity to break down electrolytes to form elements. The products of electrolysis can be predicted for a given electrolyte.

Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
Energy changes
Exothermic and endothermic reactions - AQA
Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases.
Chemical cells - AQA
A chemical cell produces a voltage until one of the reactants is used up. In a hydrogen-oxygen fuel cell, hydrogen and oxygen are used to produce a voltage, and water is the only product.
Sample exam questions - energy changes - AQA
Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
The rate and extent of chemical change
Rates of reaction - AQA
