Diamond is a giant structure of carbon atoms covalently bonded to four other carbon atoms. The bonds spread trough the structure so it is a giant structure.
Each carbon atom has four electrons in its outer shell so can form four single covalent bonds with other carbon atoms.

Key terms in this lesson
- Electron shell
- A main energy level occupied by electrons, given a principal quantum number n, with n = 1 closest to and lowest in energy relative to the nucleus.
- Covalent bond
- A strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms.
- Electron pair repulsion theory
- The theory that electron pairs around a central atom arrange themselves as far apart as possible to minimise repulsion, determining the shape of a molecule or ion.
