Graphite is an example of a material that is not a metal but still conducts electricity.
The structure of this crystalline carbon is one that is both planar and layered. Graphene is the name given to each individual layer of the same substance. Because of the possibility that the graphite’s fourth electron will move into the plane, the graphite will have an electrical conductivity that is conducive. The layers of the carbon crystal were able to quickly move past one another because the layers were easily able to be separated due to the weak van der Waals bonds that held them together.
