nitrogen and phosphorus belongs to group 15 of the periodic table write down the electronic configuration of these two elements which one of these will be more electronegative why

Nitrogen 2,5
Phosphorus 2,8,5
From this Nitrogen is more electronegative atom
On moving down a group, the number of shell increases. Therefore, the valence electrons move away from the nucleus and the effective nuclear charge decreases. This causes the decrease in the tendency to attract electron and hence electronegativity decreases.
I hope this would be the answer to your question.....
