Answer 1

Answer:

Primitive Cubic Unit Cell

In the primitive cubic unit cell, the atoms are only located on the corners. That means 8 atoms are located on 8 corners of the lattice. Each atom located on the corner contributes 1/8th of the original volume of the cell. So since there are total 8 atoms in a primitive cubic unit cell, the total number of atoms in the primitive cubic unit cell.

So there is only 1 atom in a primitive cubic unit cell.
