Why is graphene able to conduct electricity.

Graphene is a giant covalent compound made purely of carbon atoms. Within graphene each carbon atom is covalently bound to just 3 other carbon atoms. A carbon atom usually makes 4 covalent bonds. This means that within in graphene one carbon is able to delocalise its electrons which can then be used to conduct electricity.
