In which pair most efficient packing is present?

A

Hcp and bcc

B

hcp and ccp

C

bcc and ccp

D

bcc and simple cubic cell

Text Solution

Verified by Experts

The correct Answer is:
B
packing efficiency is the percentage to total filled spaces by partices and it can be calculated as packing efficeency
`("Volume occupied by spheres in the unit cell ")/("total volume of unit cell ")xx100`
since packing efficiency for hcp or ccp is calculated to be 74 % which is maximum among all type of crystals.
