    Which of the following has the smallest size

    A) \[N{{a}^{+}}\]           

    B) \[M{{g}^{+2}}\]

    C) \[C{{l}^{-}}\] 

    D) \[{{F}^{-}}\]

    Correct Answer: B

    Solution :

    [b]        As the nuclear charge per \[{{e}^{-}}\] is maximum in \[M{{g}^{+2}}\], it has smallest size among \[N{{a}^{+}},\,\,M{{g}^{+2}},\,\,C{{l}^{-}}\] and \[{{F}^{-}}\].
