In the fluorite structure the coordination number of `Ca^(2+)` ion is

A

`4`

B

`6`

C

`8`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
3
In a fluorite structure `(CaF_(2))` every `Ca^(2+)` ion is surrounded by `8` fluoride ion trapped in tetrahedral voids.Thus the `CN` of `Ca^(2+)` ions is eight .
