the correct order of the packing effeciency in different types of unit cells is ……….. .

A

fcc > bcc > simple cubic

B

fcc > bcc < simple cubic

C

fcc < bcc < simple cubic

D

bcc > fcc > simple cubic

Text Solution

Verified by Experts

The correct Answer is:
A
Packing efficiency of ccp or fcc =74%
Packing efficiency of bcc = 68%
Packing efficiency of simple cubic =52.4%
Thus, the correct order of the packing efficiency is fcc gt bcc gt simple cubic
