Key Stage 3
Meaning
Diamonds are large crystal molecules of carbon.
About Diamonds
- Diamonds are very hard.
- Diamonds are transparent.
Key Stage 4
Meaning
Diamond is an allotrope of carbon in which the atoms are bonded in a tetrahedral arrangement.
 |
| A diagram showing the arrangement of carbon atoms in diamond. |
About Diamonds
- Diamonds are a giant covalent structure.
- Diamonds are extremely hard.
- Diamonds have a high melting point.
- Diamonds are transparent and have a high refractive index.
- Diamond is a poor electrical conductor because there are no free electrons to move around the giant covalent structure.
