Why graphite is a good conductor of electricity |
|
Answer» Due to the presence of Mobile electron, this mobile electrons are always free to move through one layer to other. Graphite is a good conductor of electricity. Its structure is the main reason for this property. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds. Therefore, out of the four valence electrons in a carbon atom, only three are used for bonding and the fourth is relatively free and can move from one carbon atom to the other. These free electrons make graphite a good conductor of electricity. Graphite is a good conductor of heat. This is because graphite contains delocalised(free) electrons. |
