The unit cell of a metallic element of atomic mass 108 and density 10.5 g/ is a cube with edge length of 409 pm. The structure of the crystal lattice is-
(D) None of these
(A). Here, M=108,
Put on these values and solving we get
a= 409pm = ,
z = 4 = number of atoms per unit cell.
So, the structure of the crystal lattice is fcc.
