Question

The ionic radii of A+ and B– ions are 0.98×10–10 m and 1.81×10–10 m. The coordination number of each ion in AB is :

Answer 1

Answer:

The coordination no is 6.

Explanation:

Ra\Rb = 0.541

Now, 0.514 lies between 0.414 and 0.732 i.e.

0.414<.0514<0.732

therefore it has octahedral voids.

The coordination no in particles having octahedral voids is 6.
