In `CsCl` with cubic structure, `Cl^(-)` ions are located at each corner and `Cs^(+)` ions at the centre of the unit cell. If `r_(Cs^(+))` and `r_(Cl^(-))` and `1.69Å` and `1.81Å` respectively. Find the value of edge length of cube. |
Answer» Correct Answer - 4 `r_(Cs^(+))+r_(Cl^(-))=1.69+1.81=3.5Å` Diagonal length`=(asqrt(3))/(2)` `:. (asqrt(3))/(2)=3.5` or`a=(3.5xx2)/(sqrt(3))~~4` |
