Write the electronic configurations of these two elements. Which of these will be more electronegative ? Why?


Best Answer

Ans. Electronic configuration of Nitrogen is 2, 5.

Electronic configuration of Phosphorus is 2, 8, 5.

Nitrogen will be more electronegative than Phosphorus because its atom has small size due to which the attraction of its nucleus for the incoming electron is more.
