Question

The correct sequence which shows decreasing order of the ionic radii of the elements is

• A. \(\text{Al}^{3+} > \text{Mg}^{2+} > \text{Na}^+ > \text{F}^- > \text{O}^{2-}\)
• B. \(\text{Na}^+ > \text{Mg}^{2+} > \text{Al}^{3+} > \text{O}^{2-} > \text{F}^-\)
• C. \(\text{Na}^+ > \text{F}^- > \text{Mg}^{2+} > \text{O}_2 > \text{Al}^{3+}\)
• D. \(\text{O}^{2-} > \text{F}^- > \text{Na}^+ > \text{Mg}^{2+} > \text{Al}^{3+}\)

Answer 1

The Correct Option is D

The correct option is (D): \(\text{O}^{2-} > \text{F}^- > \text{Na}^+ > \text{Mg}^{2+} > \text{Al}^{3+}\)
