Carbon Structures - Diamond
Chemistry: AQA GCSE Higher, topic 2.3.11
Diamond
Diamond is an allotrope (form) of carbon. Diamond has the following properties:

Covalent bonds
- Every carbon atom in diamond is bonded to 4 other carbon atoms by strong covalent bonds.
- This creates a giant covalent structure.

Is diamond hard?
- There are lots of strong covalent bonds in diamond. This makes it very hard.
- Because diamond is hard, it is used as a cutting tool to cut other materials.

Does diamond conduct electricity?
- Diamond is NOT an electrical conductor because there are no delocalised electrons in the diamond structure.

What is diamond's melting point?
- A lot of energy is needed to break strong covalent bonds.
- Diamond has lots of strong covalent bonds. This means that diamond has a high melting point.

Why does diamond not conduct electricity?
Diamond contains many strong covalent bonds between its carbon atoms. How would diamond's hardness change if these bonds were much weaker?
