The radius of `A^(+)` is 0.95 `Å` and of `B^(-)` is `1.81 Å`. The coordination number of `A^(+)` is `:`

A

4

B

6

C

8

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`( r_(A^(+)))/( r_(B^(-))) = ( 0.95)/( 1.81 ) = 0.523`
Since radius ratio `( r^(+) // r^(-))` lies between 0.414 - 0.732 , the coordination number is 6.
