Question

Nitrogen (atomic number 7) and Phosphorous (atomic no. 15)
belongs to group 15 of the periodic table. Write the electronic
configuration of these two elements. Which of these will be more electronegative. Why?​

Answer 1

Answer:

Phosphorous have highest electronegativity

Explanation:

Nitrogen 1s2 2s2 2p3

Phosphate 1s2 2s2 2p6 3s2 3p3

Phosphate is S block element

S block elements have highest electronegativity

Answer 2

Answer:

Nitrogen and phosphorus belongs to group 15. the place of phosphorus is below nitrogen in the group. As we know that the electronegativity of the elements decreases a on going from top to bottom in a group, that's why nitrogen is more electronegative.
