    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 :

    \[n{{s}^{2}}n{{p}^{5}}\]configuration represents the most electronegative element as after gaining one electron it becomes more stable (inert gas configuration) [electronegativity is the tendency of attracting electron].
