In floorite structure `(CaF_(2))`

A

`Ca^(--)` ions are ccp and `F^(-)` ions are present in all the tetrabdral voids

B

`Ca^(--)` ions are ccp and `F^(-)` ions are present in all the octabehdral voids

C

`Ca^(++)` ions are ccp and `F^(-)` ions are present in all the octabehdral voids

D

None

Text Solution

Verified by Experts

The correct Answer is:
a
`Ca^(2+)` ions are ccp and `F^(-)` ions are present in the tetrehadral voids so the no of `Ca^(+)` ions is `4` and no of `F^(-)` ions in `8`
So the formula of the calcuit fluctride is `CaF_(2)`
