|---|---|
(P) Number of octahedral void present per fcc unit | (1) 2 |
(Q) It radius ratio is less than 0.155, the coordination no. is | (2) 6 |
(R) Number of tetrahedral void present per fcc unit | (3) 4 |
(S) Number of atoms per prism unit of HCP structure | (4) 8 |
Options:
Answer:
A
Solution:
(P) (3): An FCC unit cell contains 4 atoms, meaning it has exactly 4 octahedral voids ().
(Q) (1): A limiting radius ratio less than 0.155 corresponds to a coordination number of 2.
(R) (4): The number of tetrahedral voids is twice the number of atoms, giving voids.
(S) (2): A standard hexagonal close-packed (HCP) unit cell prism contains a total of 6 atoms.
