The element expected to form largest ion to achieve the nearest noble gas configuration is
1 \(\mathrm{F}\)
2 \(\mathrm{N}\)
3 \(\mathrm{Na}\)
4 \(\mathrm{O}\)
Explanation:
\({{\text{F}}^{{\text{ - 1}}}}{\text{,}}{{\text{N}}^{{\text{ - 3}}}}{\text{,N}}{{\text{a}}^{\text{ + }}}{\text{and }}{{\text{O}}^{{\text{ - 2}}}}\) all ions are isoelectronic containing \(10 \mathrm{e}^{-}\). In isoelectronic series, anion with maximum charge is largest and cation with maximum charge is smallest. radius: \(\mathrm{N}^{-3}>\mathrm{O}^{-2}>\mathrm{F}^{-}>\mathrm{Na}^{+}\)

Which one of the following has largest ionic radius?
1 \({\rm{L}}{{\rm{i}}^{\rm{ + }}}\)
2 \({\rm{O}}_{\rm{2}}^{{\rm{2 - }}}\)
3 \({{\rm{B}}^{{\rm{3 + }}}}\)
4 \({{\rm{F}}^{\rm{ - }}}\)
Explanation:
On moving along a period ionic radii decreases due to increase in effective nuclear charge.

Atomic number of \(\mathrm{Na}=11 ; \mathrm{Mg}=12 ; \mathrm{Al}=13\). Among \(\mathrm{Na}^{+}, \mathrm{Na}, \mathrm{Mg}, \mathrm{Mg}^{2+}\) and \(\mathrm{Al}^{3}\), the smallest and the biggest are respectively
1 \(\mathrm{Na} ; \mathrm{Na}^{+}\)
2 \(\mathrm{Mg}^{2+} ; \mathrm{Na}\)
3 \(\mathrm{Na}^{+} ; \mathrm{Mg}^{2+}\)
4 \(\mathrm{Al}^{3+} ; \mathrm{Na}\)
Explanation:
As number of positive charge on element increases, size decreases. Hence \(\mathrm{Al}^{3+}\) has the smallest size whereas Na has the biggest size.
