Answer:
Graphite
Explanation:
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Thats why diamond are bad conductor electricity. ... As such each carbon atom is linked with four neighbouring carbon atoms.The reason graphite is a good conductor of electricity is because of the presence of delocalised electrons, as each carbon atom forms only three covalent bonds with three other carbon atoms
