The radius of the `Na^(+)` is 95 pm and that of CI ion is 181 pm Predict the coordination number of `Na^(+)` ?

Text Solution

Verified by Experts

Radius ratio `(r^+/r^-)=95/181=0.52`
Radius ratio lies between 0.414 -0.732, hence `Na^+` ions prefer to occupy octahedral voids having Coordination number =6
