WebIn graphite, each carbon atom uses only 3 of its 4 outer energy level electrons in covalently bonding to three other carbon atoms in a plane. Each carbon atom contributes one electron to a delocalized system of electrons that is also a part of the chemical bonding. The delocalized electrons are free to move throughout the plane. WebRecall that the electronic structure of the carbon atom is 1s2 , 2s2, 2p2. The bonding electrons being referred to are the two electrons in the 2s suborbital and the two electrons in the 2p suborbital (total of 4).
