In terms of structure and bonding, explain why graphite is able to conduct electricity.
Carbon is in group 4 of the periodic table therefore has 4 electrons in its outer shell which are available for bonding. Each carbon atom in graphite forms 3 covalent bonds with another carbon atom within the structure. This results in one electron per atom being “free”. This “free” electron is known as a delocalised electron and is able to move through the structure, carrying charge therefore allowing graphite to conduct electricity.
