WebIn the solid state, a pure metal has a giant metallic structure. The atoms are arranged in layers. When a force. is applied, the layers may slide over each other. WebBecause atoms on a face are shared by two unit cells, each counts as atom per unit cell, giving Au atoms per unit cell. Atoms on a corner are shared by eight unit cells and hence contribute only atom per unit cell, giving Au atom per unit cell. The total number of Au atoms in each unit cell is thus 3 + 1 = 4.
