Q.

What is the atomic packing factor of BCC structure?

A. 0.54
B. 0.68
C. 0.74
D. 0.96
Answer» B. 0.68
Explanation: the density of packing in a crystal is determined using the atomic packing factor (apf). the apf of fcc and hcp structures is 0.74, and 0.54 for simple cubic structure, whereas it is 0.68 for bcc structure.
