(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.
