Consider the isoelectronic species, \(\mathrm{Na}^{+}\), \(\mathrm{Mg}^{2+}\), \(\mathrm{F}^{-}\) and \(\mathrm{O}^{2-}\). The correct order of increasing length of their radii is ...........
- A\(\mathrm{F}^{-}<\mathrm{O}^{2-}<\mathrm{Mg}^{2+}<\mathrm{Na}^{+}\)
- B\(\mathrm{Mg}^{2+}<\mathrm{Na}^{+}<\mathrm{F}^{-}<\mathrm{O}^{2-}\)
- C\(\mathrm{O}^{2-}<\mathrm{F}^{-}<\mathrm{Na}^{+}<\mathrm{Mg}^{2+}\)
- D\(\mathrm{O}^{2-}<\mathrm{F}^{-}<\mathrm{Mg}^{2+}<\mathrm{Na}^{+}\)
✓ Correct answer: B
