Bonding, structure and properties

In the Organic Chemistry unit, pupils will build on their knowledge of carbon chemistry to explore the vast array of natural and synthetic organic compounds and their applications.

In the Structure and Bonding unit, pupils learned about different types of chemical bonding and how these bonds affect the properties of substances.

This unit explores how material properties relate to bonding, bond strength, and structure, focusing on carbon compounds like diamond, graphite, and graphene. It covers nanoparticles, their uses and risks, surface area calculations, scale comparisons, and model representation techniques.
