How does graphite conduct electricity?

Kaiya Bird

Expert

Unlike diamond, which has four covalent bonds between each carbon atom, graphite only has three. Carbon atoms are arranged in layers in graphite.The layers slide over each other easily because there are only weak forces between them, making graphite slippery.
Graphite contains delocalised electrons (free electrons). These electrons can move through the graphite, carrying charge from place to place and allowing graphite to conduct electricity.
