Science

In the Atomic structure and the periodic table unit, pupils will build on this knowledge to learn about how the structure of atoms in each element determine its position on the periodic table and affects its chemical and physical properties.

In the Atoms, elements and compounds unit, pupils learnt about atoms, the differences between elements and compounds and how particles reorganise in a chemical reaction
