We will identify everyday events that can only be explained by matter being made up of particles. Secondly, the title will move on to look at atoms and what they are made of. It considers protons, neutrons and electrons as the building blocks of atoms. The terms 'atomic number' and 'mass number' are then explained. We will use these concepts to understand what isotopes are. After this, we will introduce the term 'relative atomic mass', before going on to consider the arrangement of the electrons in shells around the nucleus and how this can affect the chemical properties of the elements. Finally, the title looks at the terms 'element', 'mixture' and 'compound' and what they mean to scientists.
