Graphite is an allotroph of carbon and we know that carbon is a non-metal but graphite can conduct electricity so option A is the correct answer

Graphite as a good conductor of electricity

Graphite is a non-metal that is a good conductor of electricity. This is due to its unique structure, which consists of layers of carbon atoms that are arranged in a hexagonal lattice. These layers are held together by weak van der Waals forces, which allows them to slide past one another easily.

Electrons in graphite

The electrons in graphite are delocalized, meaning that they are not associated with any particular atom but are free to move throughout the entire material. This makes graphite an excellent conductor of electricity because the electrons can flow through the material easily.

Uses of graphite

Graphite is widely used as a conductor in a variety of applications, including electrical circuits, batteries, and electrodes. It is also used as a lubricant because of its slippery nature, and as a material for high-temperature applications because it can withstand extreme temperatures without melting or degrading.

Comparison with other non-metals

Other non-metals, such as phosphorus, hydrogen, and bromine, are not good conductors of electricity because they do not have delocalized electrons. Instead, the electrons in these materials are tightly bound to individual atoms, which makes it difficult for electricity to flow through them.

Conclusion

In conclusion, graphite is a unique non-metal that is a good conductor of electricity due to its delocalized electrons and unique structure. Its conductivity makes it an important material in a variety of applications, and its properties have been studied extensively by scientists and engineers over the years.
