Which of the following is correct sequence of the crystal structure with respect to percentage of voids (SCC – Simple Cubic Cell, FCC – Face Centred Cubic, BCC – Body Centred Cubic).
Correct Answer: B — FCC < BCC < SCC
Explanation:
Explanation: Atomic packing factor: In the crystal structure, the atomic packing factor (APF) or packing efficiency or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. The atomic packing factor of different crystal structures is given in the table below: Unit Cell | Coordination No.
