Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the periodic table. Write the electronic configurations of these two elements. Which of these will be more electronegative ?Why ?

Electronic Configuration of Nitrogen is (2,5) and Phosphorous is (2,8,5). Among these two nitrogen is more electronegative because nitrogen is smaller in size so the attraction between the nucleus and the incoming electron of nitrogen is more.
