Question

Nitrogen and phosphorous belong to group 10 of the periodic table. Write the electronic configuration of these two elements. Which of these will be more electronegative? Why?

Answer 1

nitrogen - 2,6
phosphorus - 2,8,6

nitrogen is most electeonegative

Answer 2

nitrogen - 2,6  - 2 shells  phosphorus - 2,8,6  - 3 shells

nitrogen is most electronegative because while going down in a group it is more electropositive series ,but opp, in electronegative series going up in a group the electronegativity increases

   :) hope the ans would help u...
