    The outermost electronic configuration of the most electronegative element is

    A)  \[n{{s}^{2}}n{{p}^{3}}\]

    B)  \[n{{s}^{2}}n{{p}^{4}}\]

    C)  \[n{{s}^{2}}n{{p}^{5}}\]         

    D)  \[n{{s}^{2}}n{{p}^{6}}\]

    Correct Answer: C

    Solution :

    Fluorine is the most electronegative element and its electronic configuration is as \[{{F}_{9}}=1{{s}^{2}},2{{s}^{2}},2{{p}^{5}}\] Thus, its outer electronic configuration is \[n{{s}^{2}}n{{p}^{5}}\].
