Question
An element occurring in the body-centred cubic (BCC) structure has 1.208 × 10^23 unit cells. The total number of atoms of the element in these cells will be
Answer: A
💡 Solution & Explanation
A body-centered cubic (BCC) unit cell contains an effective number of 2 atoms (Z = 2). Therefore, total atoms = 2 atoms/cell * (1.208 × 10^23 unit cells) = 2.416 × 10^23 atoms.
