What is the volume of the atom of an element that crystallizes as a body-centered cube if the volume of the unit cell is 1.97 x 10-22 cm3 ?

Volume of unit cell=1.97*10-22 m3

Volume occupied by atoms=68.02% of volume of unit cell

  =0.6802*1.97*10-22=1.34*10-22 m3

Volume of 1 atom=0.5*volume occupied by atoms in single unit cell

  =0.5*1.34*10-22=6.70*10-21 m3
