What is the number of atoms per unit cell for each

Solution 67P

Here we have to find out  the  number of atoms present per unit cell for each metal.

Step 1

(a) Polonium, Po

The structure of Po shows a simple cubic unit cell. In simple cubic unit cell, 8 atoms are present in 8 corners of the unit cell and each atom is shared by 8 unit cells. Therefore, the contribution of each corner atom to each unit cell is ⅛.

Total atom per unit cell can be calculated as,

⅛  8 = 1

Therefore the number of atoms in simple cubic unit cell of Po atom is  1.
