This element is crystalline in nature; however perfect crystals of graphite are rarely found. The carbon atoms in its structure are arranged in a hexagonal manner in a planar condensed ring system. This gives the graphite crystals a hexagonal shape. Different layers of this element are stacked together and held by weak covalent forces to form a giant covalent structure. Melting Point
