Question

valence electron of carbon atom in graphite localized to specific covalent bond​

Answer 1

Valence electrons in a carbon atom in graphite are localized to a specific covalent bond. This can be explained as follows:

• There are four valence electrons in the excited state of carbon.

• In graphite, carbon forms only three covalent bonds with three adjacent carbon atoms in one layer leaving one electron free.

• Due to this free electron graphite becomes a good conductor of electricity.
