    Solution-

    (A) Atomic number of the element = 2+8+7

                                                             = 17

    (B) Electronic configuration of 

                   N (7) = 2,5

                   F (9) = 2,7

                   P (15) = 2,8,5

                   Ar (18) = 2,8,8

    It will be similar to fluorine because like fluorine it also contains 7 electrons in its valence shell (F =2,7)
