Graphite conductor
WebJul 7, 2024 · Advertisement Graphite is the one ‘allotropic form’ of carbon. In a graphite molecule, one valence electron of each carbon atom remains free. Due to the free electrons in its framework, graphite can perform electricity. Therefore, graphite is said to be a good conductor of electricity. Why is graphite a goodRead More → WebBecause the fourth electron of each carbon atom is unbound, graphite conducts electricity. As a result of the existence of free electrons in the structure, we may deduce that …
