Question

Name

b.non-metal which is a good conductor of electricity.

Answer 1

1. For the conduction of electricity, a substance must have free electrons.
2. Due to the presence of free electrons in the structure of graphite, it is a good conductor of electricity.
3. In a graphite molecule, one valence electron of each carbon atom remains free.
4. This free electron in its structure is the reason behind the electric conductivity in graphite.

Thus, graphite, a non-metal, is a good conductor of electricity.
