a) A monoatomic BCC crystal

It has 8 atoms at each corner and one at body centre which is not shared by other cells. Number of atoms per unit cell in BCC is

b) A monoatomic SC crystal

Simple cubic cell is shared by 8 cells and therefore its average contribution to one cell is 1/8 and Number of atoms per unit cell in SC is 1

c) CsCl crystal
