Question

The radius of Ag+ ion is 126 pm while that of lion
is 216 pm. The co-ordination number of Agt in Agl
is expected to be​

Answer 1

Answer:

The co-ordination number of Ag in AgI is 6.

Explanation:

Radius ratio

Radius of  ion = 126 pm

Radius of  ion = 216 pm.

Radius ratio =

The ratio comes in the range of 0.414 to 0.732 of octahedral structural arrangement which means the coordination number is 6.

The co-ordination number of Ag in AgI is 6.
