    Decreasing size of ions is:

    A) \[\text{I}\,\text{}\,{{\text{I}}^{-}}>{{I}^{+}}\]                    

    B) \[\text{I}{{\,}^{-}}\text{}\,\text{I}>{{I}^{+}}\]

    C) \[\text{I}{{\,}^{+}}\text{}\,{{\text{I}}^{-}}>I\]    

    D)        \[\text{I}\,\text{}\,{{\text{I}}^{+}}>{{I}^{-}}\]

    Correct Answer: B

    Solution :

    Key Idea: The size of cation is always smaller than corresponding neutral atom and anion is always larger in size the corresponding neutral atom. \[\therefore \]\[{{I}^{-}}>I>{{I}^{+}}\]is correct order.
