Question:
Among the ions O$^{2-}$, Na$^+$, F$^-$, N$^{3-}$, Mg$^{2+}$ the ions with smallest and largest radii are respectively
Among the ions O$^{2-}$, Na$^+$, F$^-$, N$^{3-}$, Mg$^{2+}$ the ions with smallest and largest radii are respectively
Show Hint
More the negative charge, larger the radius.
More the positive charge, smaller the radius.

- F$^-$, N$^{3-}$
- Mg$^{2+}$, N$^{3-}$
- Na$^+$, F$^-$
- F$^-$, Na$^+$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Mg$^{2+}$ has highest effective nuclear charge among given ions, so it has the smallest size. N$^{3-}$ has least nuclear pull per electron, hence largest.
