In a closed packed structure of mixed oxides, the lattice is composed of mixed oxides ions. One-eighth of tetrahedral voids are occupied by divalent cation `(A^(2+))` while one-half of octahedral voids are occupied by trivalent cations `(B^(3+))`. The fromula of mixed oxide is

A

`ABO_(4)`

B

`AB_(2)O_(4)`

C

`AB_(2)O`

D

`ABO`

Text Solution

Verified by Experts

The correct Answer is:
B
For per oxide ion in unit cell:
Number of tetrahedral voids per ion in lattice=2
Number of divalent cation (A)
Number of octahedral voids per ion in lattice=1
Number of trivalent cations(B)
Formula =`A_(1//4)B_(1//2)O=AB_(2)O_(4)`
