The graphite form of carbon has an unusual property for a non- metal. what property is it?

The graphite can conduct electricity

Explanation:

The main building element of graphite is carbon atoms. The carbon has 4 outer electrons. In graphite, the three electrons are bonded to the other carbon atoms. One electron remains free.

So, if there is a free electron in a substance, it can conduct electricity.

This property of graphite makes them special among the other non-metals. Actually, non-metals don't conduct heat and electricity.

This nature of Graphite makes it as the only non-metal that can conduct electricity.

that would be b i just took the test : )
