Refers to the force of attraction between atoms or ions that hold them together.

Refers to any force that causes two or more substances to come together.

Structures in chemistry are determined by the type of bonding and arrangement of atoms or ions.

A feature or characteristic of a substance that can be used to classify it, or describe how it behaves.

Particles that enable electrical conductivity, such as delocalised electrons or free–moving ions.

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.

Match the following structures to the type of bonding.

To attain a stable electron configuration.

Electrons are transferred, so charged ions, not atoms, are bonded.

Electrons are delocalised among a lattice of metal ions.

Match the type of bonding to its description:

What type of bonding can be found between non–metal atoms?

From the diagrams below, select the image depicting a substance with ionic bonding.

The sharing of electron pairs equally between atoms.

The complete transfer of electrons between atoms to form charged ions.

The pooling of electrons in a 'sea' around a network of ions.

The presence of a dipole moment due to unequal electron sharing.
