Meaning

Graphites is a soft black material made of pure carbon.

About Graphite

Graphite is very soft.
Graphite is used in pencils.

Key Stage 4

Meaning

Graphite is an allotrope of carbon in which the atoms are bonded in layers with a hexagonal arrangement.

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.
