WebGraphite is layered. Within each layer, carbon atoms form strong covalent bonds in a hexagonal pattern (planar). A covalent bond is one in which one or more pairs of bonding electrons (valence) are shared. Carbon forms a double covalent bond, which means that two pairs of bonding electrons are shared. This type of bond is very strong.
