WebHexagonal close packed (hcp) is one of the two simple types of atomic packing with the highest density, the other being the face centered cubic (fcc). However, unlike the fcc, it is not a Bravais lattice as there are two nonequivalent sets of lattice points. Metals containing HCP structures include beryllium, magnesium, zinc, cadmium, cobalt ... WebThe structures of crystalline metals and simple ionic compounds can be described in terms of packing of spheres. Metal atoms can pack in primitive cubic, body-centered cubic, and face-centered cubic structures. Each packing has its own characteristics with respect to the volume occupied by the atoms and the closeness of the packing.
