Vedclass · Answer

(B) In a $ZnS$ type crystal structure, the cations $(A^{+})$ occupy the tetrahedral voids.For tetrahedral voids, the limiting radius ratio is given by:$\frac{r_{+}}{r_{-}} = 0.225$Given that the radius of $A^{+}$ $(r_{+})$ is $22.5 \ pm$, we can calculate the radius of $B^{-}$ $(r_{-})$ as follows:$r_{-} = \frac{r_{+}}{0.225} = \frac{22.5 \ pm}{0.225} = 100 \ pm$.Therefore, the ideal radius of $B^{-}$ is $100 \ pm$.

An ionic compound $AB$ has $ZnS$ type structure. If the radius of $A^{+}$ is $22.5 \ pm$, then the ideal radius of $B^{-}$ would be .............. $pm$.
