Diamond is the hardest natural substance on Earth.
Why is diamond so strong?
Diamond is made up of a network of carbon atoms that each form four strong covalent bonds. The strong bonds take a lot of energy to break, so diamond has a high melting and boiling point.
This type of structure is called a giant covalent structure, as all the carbon atoms are bonded to each other by strong covalent bonds.
The strong covalent bonds also hold the atoms in a rigid lattice structure, which makes diamond very hard.
Uses of diamond
In cutting tools
Jewellery
