Question

the radius of Ag+ ion is 126pm while that of i-ion is 216pm. the C.N of Ag in AgI?​

Answer 1

Answer:

CN 6

Explanation:

r+/r- =126/216

=0.58

any radius ratio that lie between 0.414 and 0.732 have Coordination number 6

Hope it helps

I'm new here I will try to answer as much as I can so do follow me for more and if you think my answer is worth please Rate it

Answer 2

Answer:

Radius ratio

Radius of  ion = 126 pm

Radius of  ion = 216 pm.

Radius ratio = r+/r- = 126/216 = 0.5833

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.
