Solid copper can be described as the arrangement of copper atoms in a face-centered-cubic (fcc) configuration. A copper atom is found at each corner and in the center of each face of a cube as depicted in Figure 1. This is the unit cell which is repeated in three dimensional space to make up the crystal structure of the metal. The atoms are held in place in the structure by the energy of the atomic attractions between them.
