Why can graphite conduct electricity but not diamond
Graphite on the other hand although also only made up of carbon atoms is the only non metal that can conduct electricity This is because only 3 of the available valence electrons form covalent bonds leaving 1 spare electron which then becomes delocalised This delocalised electron is no longer associated with one particular carbon atom and

Question Why Is Graphene More Conductive Than Graphite
Graphite is an electrical conductor hence useful in such applications as arc lamp electrodes It can conduct electricity due to the vast electron delocalization within the carbon layers a phenomenon called aromaticity These valence electrons are free to move so are able to conduct electricity
