Asked by Topperlearning User | 16 Jun, 2016, 03:32: PM
Expert Answer
Face centred cubic unit cell has points at all the corners as well as at the centre of each of the six faces. The contribution of each atom at the face per unit cell is ½ and at each corner is 1/8.
So, number of atoms present at corners per unit cell = 8 corner atoms x atom per unit cell = 1 atom
Number of atoms present at faces per unit cell = 6 atoms at faces x atom per unit cell = 3 atoms
Total no. of atoms per unit cell = 4 atoms.
