Key Stage 3
Meaning
Graphites is a soft black material made of pure carbon.
About Graphite
Key Stage 4
Meaning
Graphite is an allotrope of carbon in which the atoms are bonded in layers with a hexagonal arrangement.
 |
| A diagram showing the arrangement of carbon atoms in graphite. |
About Graphite
- Graphite is a giant covalent structure.
- Graphite is very soft.
- Graphite has a high melting point.
- Graphite is a good electrical conductor because it only uses 3 out of the 4 electrons in the outer shell to bond with other atoms allowing the last electron to move freely around the giant covalent structure.
