The ionic radii of Rb^(+) and I^(-) are ...

The ionic radii of `Rb^(+)` and `I^(-)` are 1.46 and `2.16Å`. The most probable type of structure exhibited by it is:

A

CsCl type

B

NaCl type

C

ZnS type

D

`CaF_(2)`type

Text Solution

Verified by Experts

The correct Answer is:
B
`r^(+)//r^(-)`=`1.46//2.16=0.67`.The structure should be NaCl type.
