1.	Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of thePeriodic Table. Write the electronic configuration of these two elements. Which of these will be more electronegative? Why?
Answer» SOLUTION : (a) NITROGEN (N) - At. No. = 7, ELECTRONIC configuration = 2,5. (b)Phosphorous (P) - At. No = 15, Electronic configuration = 2, 8,5. Thus, nitrogen will be more electronegative because its atom has SMALL size due to which theattraction of its NUCLEUS for the incoming electron is more.
