A thermal conductor is a substance that transfers heat from one place to another place.

An electrical conductor is a substance that allows a flow of charge (electrical current).

A malleable substance has the ability to be formed into a shape.

A brittle substance has the ability to break up easily.

A ductile substance has the ability to be pulled into a wire.

In the Understanding Chemical Reactions unit, pupils will build on their knowledge of atoms, elements, and compounds to learn about how atoms rearrange to form new substances during chemical reactions.

In the Solid, Liquid and Gas States and Changes of State unit, pupils learned to categorise substances and understand particle behaviour during changes of state.

This unit explores the basic atomic model, the differences between atoms, elements, and compounds, and the varying physical and chemical properties of elements. It covers chemical symbols, formulae, SI units, and IUPAC nomenclature, emphasising their use in describing elements and compounds.
