WebGraphite is a giant covalent substance in which: each carbon atom is joined to three other carbon atoms by covalent bonds the carbon atoms form a hexagonal layered network structure the... WebGraphite contains layers (x-y planes) in which carbon atoms are held together with sigma bonds. Every carbon atom in this layer is bonded to three other carbon atoms to form sp2 hybridized orbitals and trigonal plane geometry. These sigma bonds are strong, and the layers contain delocalized electrons as a result of the hybridization.
