Question

An element occurring in the body-centred cubic (BCC) structure has 1.208 × 1023 unit cells. The total number of atoms of the element in these cells will be

Options

A.2.416 × 1023
B.3.618 × 1023
C.6.04 × 1022
D.1.208 × 1023

Solution

For BCC: Z = 2

∴ Number of atoms = 2 × 1.208 × 1023 = 2.416 × 1023
