Question

Calculate the radius ratio of rNa+ 0.95 A0 and rcl- 1.81A0​

Answer 1

Answer:

Given, radius of Na+

(r +)=95 pm

Radius of Cl−

(r - )=181 pm

We know that,

Radius ratio= Radius of anion (r − )

Radius of cation (r+)

=181

95=0.523

This value lies between 0.414–0.732 range, so the coordination number of Na will be 6 as predicted by radius ratio rule.
