Explanation:
- Carbon atoms have 4 valence electrons that are available for bonding. In graphite, each carbon atom is covalently bonded to 3 other carbon atoms. Therefore, every carbon atom has 1 electron that is not used for bonding. These extra electrons are delocalised, or free to move, in the area between layers of carbon atoms.
