If radius of anion is `0.20nm`, the maximum radius of cations which can be filled in respective voids are correctly matched in `:`A. `r^(+)=0.045nm` triangular voidB. `r^(+)=0.0828nm` for tetrahedral voidC. `r^(+)=0.1464nm` for octahedral voidsD. none of these

Answer» Correct Answer - a,b,c
`(r^(+))/(r^(-))` maximum for triangular, tetrahedral and octahedral are `0.225,0.414` and `0.732` respectively.
