Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to

1.	Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the periodic table. Write the electronic configuration of these two elements. Which of these will be more electronegative and why ?
Answer» (i) Nitrogen: K shell-2 L shell-5 Phosphorus: K shell-2 L shell - 8 M shell-5 (ii) Phosphorus will be less electronegative because its elections are further away from the nucleus and thus nucleus can be easily lost.
