Chemistry - Solid State Question with Solution | TestHub

A⁺cation is filled in octahedral hole generated by X^-anion
i.e.,$\frac{{\text{r}}_{{\text{A}}^{+}}}{{\text{r}}_{{\text{X}}^{-}}}=\text{0.414}$
${\text{r}}_{{\text{A}}^{+}}=\text{0.414}\times 250=\text{103.5}\text{ pm}$
$\approx 104\text{pm}$
