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
Answer & Solution
Correct Answer
(B) 8,4
Step-by-step Solution
Detailed explanation
In a closed packed structure [CCP or HCP] if there are \(n\) spheres (atoms or ions) in packing; then; Number of octahedral voids \(=n\) Number of tetrahedral voids \(=2 n\) In CCP; Number of atoms \(=4\) So number of octahedral voids \(=4\) Number of tetrahedral voids \(=8\)
