- C \(23 \%\)
- D \(32 \%\)
Answer & Solution
Correct Answer
(D) \(32 \%\)
Step-by-step Solution
Detailed explanation
In a body-centered cubic (BCC) unit cell, the number of atoms per unit cell is \(Z = 2\). The relation between the edge length \(a\) and the atomic radius \(r\) is given by \(4r = \sqrt{3}a\), which implies \(r = \dfrac{\sqrt{3}a}{4}\). The volume occupied by the atoms is…
