A solid AB has ZnS type structure. If the radius of cation is 50 pm, calculate the maximum possible value of the radius of anion B− .

Question 1

Question 2

Given: Radius of cation (r+ ) = 50 pm

To find: Radius of anion (r− ) = ?

Formula: Radius ratio = Radius of the cation/Radius of the anion

Calculation: ZnS has tetrahedral arrangement.

The range of r+/r- for stable four fold coordination is 0.225 to 0.414

Hence the radius of anion can be calculated by
