WebThe crystal structure is based on the Bravais lattice of the same name, with a single atom at each lattice point on the cube’s corners and faces. FCC is one of the most stable crystal structures and has the highest packing density. In some textbooks, FCC may also be abbreviated as CCP, which stands for Cubic Close-Packed.

WebThe Body-Centered Cubic (BCC) crystal structure is one of the most common ways for atoms to arrange themselves in metals. The BCC crystal structure is based on the Bravais lattice of the same name, with 1 atom per lattice point at each corner of the cube and the center of the cube. WebThe structures of pure metals are easy to describe because the atoms can be thought of as identical perfect spheres. These substances all crystallize in one of four basic structures known as simple cubic (SC), body-centered cubic (BCC), hexagonal closest packed (HCP), and cubic closest packed (CCP).
