For an ionic crystal of the formula `AX` and cooradition number `6`, the value of radius ratio will be

A

greater than `0.73`

B

In between `0.41 and 0.22`

C

in between `0.73 and 0.41`

D

Less than `0.22`

Text Solution

Verified by Experts

The correct Answer is:
c
The srtructure arrangement of coordanation number `6` is octabedral and the radius ratio is `0.414 - 0.732` .The example of octabedral is `KCI` and `NaCI`.
