WebThe face-centred cubic (FCC) has a coordination number of 12. One-eighth of an atom at each of the eight corners i.e 8 × 1 / 8 = 1 atom from the corners. One-half of an atom on each of the six faces i.e 6 × 1 / 2 = 3 atoms from the faces. Hence, there is a total of 4 atoms in a face centred cubic unit cell. Suggest Corrections.
