    The electronic structure of four elements A, B, C, D are
    [A] \[1{{s}^{2}}\]                               
    [B] \[1{{s}^{2}},\,\,2{{s}^{2}},\,\,2{{p}^{2}}\]
    [C] \[1{{s}^{2}},\,\,2{{s}^{2}},\,\,2{{p}^{5}}\]        
    [D] \[1{{s}^{2}},\,\,2{{s}^{2}},\,\,2{{p}^{6}}\]
    The tendency to form electrovalent bond is largest in

    A) A                                 

    B) B

    C) C                                 

    D) D

    Correct Answer: C

    Solution :

    Element C has electronic structure \[1{{s}^{2}},\,\,2{{s}^{2}},\,\,2{{p}^{5}},\] it requires only one electron to complete its octet and it will form anion so it will form electrovalent bond.
