    Which of the following has maximum ionization energy?

    A)  \[(I,{{I}^{+}})\]

    B)  \[(Br,B{{r}^{+}})\]

    C)  \[(Li,L{{i}^{+}})\]

    D)  \[(Cu,C{{u}^{+}})\]

    Correct Answer: B

    Solution :

     lonization energy increases on moving from left to right in period, but on moving from top to bottom in group the ionization energy decreases. Hence, the ionization energy of \[Br\to B{{r}^{+}}+{{e}^{-}}\]will be maximum.
