A solid AB has NaCl structure. If the radius of cation `A^(+)` is 170 pm, calculate the maximum possible radius of the anion.

Text Solution

Verified by Experts

The correct Answer is:
410.16 pm
For NaCl, N.C. is 6
Radius ratio `r^(+)//r^(-)=0.414` (For maximum radius of anion).
`(("170 pm"))/(r^(-))=0.414 or r^(-)=(("170 pm"))/(0.414)=410.16"pm"`
