  • question_answer
    \[N{{a}^{+}},\ M{{g}^{2+}},A{{l}^{3+}}\] and \[S{{i}^{4+}}\] are isoelectronic. The order of their ionic size is

    A) \[N{{a}^{+}}>\ M{{g}^{2+}}<A{{l}^{3+}}<S{{i}^{4+}}\]

    B) \[N{{a}^{+}}<\ M{{g}^{2+}}>A{{l}^{3+}}>S{{i}^{4+}}\]

    C) \[N{{a}^{+}}>\ M{{g}^{2+}}>A{{l}^{3+}}>S{{i}^{4+}}\]

    D) \[N{{a}^{+}}<\ M{{g}^{2+}}>A{{l}^{3+}}<S{{i}^{4+}}\]

    Correct Answer: C

    Solution :

    [c] Among the isoelectronic species, the cation having more positive charge would be the smaller in size.
