Correct Answer: D
Solution :
In a 'fcc' crystal atoms are located at the centre of the 6 faces and at the 8 comers. On each face their is 1 atom which is shared by 2 cells. Hence, the no. of atoms/ unit cell = 6/2 = 3 Again the comer atom is shared by 8 other cells. Hence no. of atoms = 8/8 = 1 No. of atoms/unit cell = 1 + 3 = 4You need to login to perform this action.
