An hcp and a ccp structure for a given element would be expected to have

A

The same coordination number

B

The same density

C

The same packing fraction

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
A, C
The hcp and ccp structures have same `CN(12)`, same packing fraction `(0.74)`. but different density as the number of atoms as well as the volume of unit cell differ in both.
