MCQ
The ionic radii of $\mathrm{F}^{-}$ and $O^{2-}$ respectively are $1.33\, A^o$ and $1.4\, A^o$, while the covalent radius of $\mathrm{N}$ is $0.74\,A^o$
The correct statement for the ionic radius of $\mathrm{N}^{3-}$ from the following is :
- AIt is bigger than $\mathrm{F}^{-}$and $\mathrm{N}$, but smaller than of $\mathrm{O}^{2-}$
- BIt is smaller than $\mathrm{O}^{2-}$ and $\mathrm{F}^{-}$, but bigger than of $\mathrm{N}$
- ✓It is bigger than $\mathrm{O}^{2-}$ and $\mathrm{F}^{-}$
- DIt is smaller than $\mathrm{F}^{-}$and $\mathrm{N}$
