1.	`Na` and `Mg` crystallize in bcc- and fcc-type crystals, respectively, then the number of atoms of `Na` and `Mg` present in the unit cell of their respective crystal isA. 4 and 2B. 9 and 14C. 14 and 9D. 2 and 4
Answer» Correct Answer - D bcc has atoms at corner and body centre . Hence , total number of atoms = 2 and in fcc, atoms are present at corner and faces hence, total number of atoms = 4
