WebAug 24, 2024 · The fourth one remains as a free electron. After the graphite structure is created, all the free electrons can move throughout the structure without any problem. As a result, they are also affected by current or voltage sources. So when they are connected to a voltage source, the electrons start to move, making them highly conductive. WebThe fourth electron is free to wander over the surface of the sheet making graphite an electrical conductor. The spacing between the sheets of carbon atoms is greater than the diameter of the individual atoms. Weak bonding forces called van der Waals forces hold the sheets together.
