A molecular allotrope of carbon. Each atom is covalently bonded to three others, forming nanoparticles with hollow spheres or tubes.

An allotrope of carbon consisting of a sheet that is one-atom-thick. Each atom is covalently bonded to three others arranged in hexagonal rings.

A cylindrical fullerene, essentially a tube of graphene. A nanoparticle known for its strength and electrical conductivity.

Discovery and uses of carbon nanostructures

Combined science

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.
