`ThO_(2)` exists in fluorite structure, what is the effective numver of bivalent ion in the unit cell of `ThO_(2)`?

A

`2`

B

`4`

C

`1`

D

`8`

Text Solution

Verified by Experts

The correct Answer is:
D
In fluorite-type stucture, `CN = (8:4)` (cation:anion)
`(Th^(4+):O^(2-))`
Formula `= 4ThO_(2) = Th_(4)O_(8) (Z_(eff) = 4)`
`CN` of cation `=` Number of effective anion `= 8 (O^(2-))`
`CN` of anion `=` Number of effective cation `= 4 (Th^(4+)`
