WebbSolution: Radii of anion is more than neutral element. Here, O−2 has 10e− and F − has 10e− for. isoelectronic species radius increases as pe− ratio increases. ∵ O−2 pe = 810. ∴ F − pe = 910. So, radius order is O2− > F −. On moving left to right in a period, effective nuclear charge increases as radius decreases.
WebbThe correct option is C. 1.71, 1.40 and 1.36. N 3 ¯, O 2 ¯ and F¯ are isoelectronic. But due to the difference in their nuclear charges, their ionic radii follow the order N 3 ¯ > O 2 ¯ > F¯.
