    The electronic configuration of a element is as \[1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},3{{d}^{10}},4{{s}^{2}},4{{p}^{3}}\]The property of this element is similar to

    A)  boron            

    B)  oxygen

    C)  nitrogen          

    D)  chlorine

    Correct Answer: C

    Solution :

     The electronic configuration of given element is as \[1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},3{{d}^{10}},4{{s}^{2}},4{{p}^{3}}\] This is the element of fifth group because there are five electron in outermost shell. Hence, the property of this element is similar to nitrogen family.
