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.
