The radius of `Na^+` ion is 95 pm and that of `Cl^-` ion is 181 pm. Predict whether the Co-ordination of `Na^+` ion is 6 or 4

A

4

B

6

C

8

D

unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B
Radius ratio lies between `0.414" to "0.732`. Hence co-ordination number of `Na^(+)`is 6.
