Graphite is a good conductor of electricity. It is because
Linear structure
tetrahedral structure
trigonal planer structure
hexagonal multilayer structure
hexagonal multilayer structure
Since graphite is a crystalline solid it can be defined by a basic unit cell. Graphite is hexagonal and therefore is defined by a hexagonal unit cell. … Since each unit cell contains โcenteredโ and โedgeโ carbon atoms the unit cell is considered a โcenteredโ unit cell as opposed to a primitive unit cell.
