Bravais lattices<\/strong>. Three relatively simple crystal structures are found for most of the common metals.<\/p>\nHexagonal Close-packed<\/h2>\n
In a hexagonal close-packed<\/strong> (hcp) arrangement of atoms, the unit cell consists of three layers of atoms. The top and bottom layers contain six atoms at the corners of a hexagon and one atom at the center of each hexagon. The middle layer contains three atoms nestled between the atoms of the top and bottom layers. Hence, the name is close-packed. Hexagonal 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, thallium, and zirconium. HCP metals are not as ductile as FCC metals.<\/p>\n<\/div><\/div>\n\n
