Question

nitrogen and phosphorus which is more electronegative

Answer 1

Heya!!!

Nitrogen 2,5
and phosphorus is 2,8,5.
Both of these have same Valency but the number of shells is different.

Electronegativity is the property when the atom is able to gain electrons.

Nitrogen will gain electrons easily Bcoz its outermost shell is closer to the nucleus.


So, nitrogen is more electronegative.



Thank you...

Answer 2

• Only highly electrnegative elements can make nitrogen exhibit +5 oxidation state

1. We know that, on going from top to bottom in a group, non- metalllic character decreases. The non- metallic character of any element is characterized by its tendency to lose electron i.e electronegativity.
2. Hence, electronegativity decreases on going from top to bottom in a group.
3. Therefore, Nitrogen is more electronegative than Phosphorus.

1. Also, Nitrogen is smaller in size as compared to Phosphorus. Due to its small size, the net electron charge increases. Hence, its nucleus exerts greater force on the electrons.
2. Thetefore, its tendency to gain electron is more as compared to that of Phosphorus.
3. That is the reason why, Nitrogen is more electronegative element than Phosphorus.
