A malleable substance can be hammered or pressed into shape without breaking.

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

Electrons are said to be delocalised when they are free to move through the structure of a metal and can carry an electrical current.

A conductor is a substance that allows charge or energy to flow through it easily due to the presence of delocalised electrons.

A force of attraction refers to the strength of the pull between two objects either due to their mass, their charge or the presence of magnetic poles.

In the Chemistry of Carbon unit, pupils will build on their understanding of chemical bonding to explore the unique properties and bonding of carbon, leading to various natural and synthetic organic compounds.

In the Atomic Structure and the Periodic Table unit, pupils learned about the model of the atom, isotopes, and the arrangement of elements in the periodic table.

This unit explores changes of state, particle kinetics, and energy transfers in relation to chemical bonding, including ionic, covalent, and metallic bonds. It examines carbon's unique bonding properties, leading to organic compounds and materials like diamond, graphite, fullerenes, and graphene.
