Question

If for a particular compound AB, radius of A+ is 80 pm and radius of B– is 200 pm then location of A+ in the crystal and % occupancy respectively is 1. tetrahedral, 100% 2. octahedral 50% 3. tetrahedral 50%

Answer 1

Explanation:

here is your answer

Answer 2

Now in this question we will use [ρ= r small/r large ] to predict the coordination number.

here,ratio is [ρ= 88/200]=0.44

As we know if radius ratio is between 0.41 to 0.73 then the coordination number of the ion will be 6.
