The number of tetrahedral and octahedral voids in CCP unit cell are respectively

A

4,8

B

8,4

C

12,6

D

6,12

Text Solution

Verified by Experts

The correct Answer is:
B
Answer(2) If number of atoms in ccp = n,
Then, number of tetrahedral voids = 2n .
Number of octahedral voids = n .
`therefore` option (2) is correct. .
Number of atoms = Number of octahedral voids = 4 .
Number of tetrahedral voids = 8.
