The body-centered cubic unit cell has atoms at each of the eight corners of a cube  plus one atom in the center of the cube. Corners will always be 1/8 and 1 in the center.

8 corners x 1/8 = 1 and Body center = 1x1 therefore total 2 atoms per unit cell. So  the unit cell of the element will have 2 atoms.
