A) a decrease from \[{{O}^{2-}}\] to \[{{F}^{-}}\]and then increase from \[N{{a}^{+}}\]to \[A{{l}^{3+}}\]
B) a significant increase from \[{{O}^{2-}}\]to \[A{{l}^{3+}}\]
C) a significant decrease from\[{{O}^{2-}}\]to \[A{{l}^{3+}}\]
D) an increase from\[{{O}^{2-}}\] to \[{{F}^{-}}\]and then decrease from \[N{{a}^{+}}\] to \[A{{l}^{3+}}\]
Correct Answer: C
Solution :
[c] : Ionic radii of isoelectronic ions decrease with increase of nuclear charge thus, it shows a decrease from \[{{O}^{2-}}\] to \[A{{l}^{3+}}\]You need to login to perform this action.
