Chemical Sciences

Mixtures, including solutions, contain a combination of pure substances that can be separated using a range of techniques 

Properties of the different states of matter can be explained in terms of the motion and arrangement of particles 

Differences between elements, compounds and mixtures can be described at a particle level 

Chemical change involves substances reacting to form new substances

All matter is made of atoms that are composed of protons, neutrons and electrons; natural radioactivity arises from the decay of nuclei in atoms 

Chemical reactions involve rearranging atoms to form new substances; during a chemical reaction mass is not created or destroyed

Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer 

The atomic structure and properties of elements are used to organise them in the Periodic Table

Different types of chemical reactions are used to produce a range of products and can occur at different rates
