Q. For an ionic crystal of the general formula $AX$ and coordination number 6, the value of radius ratio will be
A) in between 0.732 and 0.414
B) in between 0.414 and 0.225
C) less than 0.225
D) greater than 0.732
Explanation
(a)
The structure arrangement of coordination number 6 is octahedral and its radius ratio is $0.414 - 0.732$. The example of octahedral is $KCl$ and $NaCl$
