Question

Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of modern periodic table। 1) write the electronic configuration of these two elements। 2) which of this will be more electro negative and why? ​

Answer 1

2:- Nitrogen is electro nagative because

1:-[N(7)=2,5 and P(15):- 2,8,5 ] electronic Configuration is Nitrogen

Answer 2

Answer:

Nitrogen is more electronegative than phosphorus.

Explanation:

More electronegativity of Nitrogen is because of it's smaller size than Phosphorus. Because of it's smaller size, Nitrogen's net electrons charge increase. Because Nitrogen's nucleus exert more force on outer electrons then Phosphorus exerts on it's outermost electrons, hence more electronegetive.
