Lera25 [3.4K]

Explanation:

It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.

Therefore, in one simple cubic unit cell sharing of one atom is only \frac{1}{8}.

Hence, the total number of atoms in a unit cell will be as follows.

            8 \times \frac{1}{8} = 1

Thus, we can conclude that there is 1 calcium atom present in each unit cell.
