The arrangement mode of carbon atoms in the graphene is bonded by an sp2 hybridization orbit like a graphite monoatomic layer, and the graphene is characterized in that the carbon atoms have 4 valence electrons, wherein 3 electrons generate sp bonds, namely each carbon atom contributes one unbonded electron positioned on a pz orbit, the pz orbitals of adjacent atoms form pi bonds in a direction vertical to a plane, and the newly formed pi bonds are in a half-filled state. Research proves that the coordination number of carbon atoms in the graphene is 3, the bond length between every two adjacent carbon atoms is 1.42 multiplied by 10 meters, and the included angle between bonds is 120 degrees.
