- A There are equal number of octahedral and tetrahedral voids in a unit cell.
- B The tetrahedral voids are present at the edge centers
- C Octahedral voids are present at the body center and edge centers.
- D Its packing efficiency (PE) is higher than hcp lattice PE.
Answer & Solution
Correct Answer
(C) Octahedral voids are present at the body center and edge centers.
Step-by-step Solution
Detailed explanation
(a) There are equal number of octahedral and tetrahedral voids in a unit cell for fcc lattice is incorrect statement. The number of octahedral and tetrahedral void in unit cell for fcc lattice is 4 and 8 respectively. (b) The tetrahedral voids are present at the edge centers is…
