Question

explain the structure of graphite why is it a good conductor of electricity whereas diamond is not though both contain only carbon atoms​

Answer 1

Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. ... However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.
