    Which one of the following ions has the highest value of ionic radius?

    A)  \[{{O}^{2-}}\]         

    B)  \[{{B}^{3+}}\]

    C)  \[L{{i}^{+}}\]             

    D)  \[{{F}^{-}}\]

    Correct Answer: A

    Solution :

    \[{{O}^{2-}}\] has the highest value of ionic radius and this can be explained on the basis of Z/e (Nucleus charge/No, of electron) ratio when Z/e ratio increases, the size decreases and when Z/e ratio decreases, the size increases.
