Question

nitrogen (atomic number 7) and phosphorus (atomic number 15)belong to group 15 of tha periodic Table. write tha electronic configuration of these two elements. which one of these will be more electronegative? why?​

Answer 1

Answer:

Electronic configuration of Nitrogen is 2, 5.

Electronic configuration of Nitrogen is 2, 5.Electronic configuration of Phosphorus is 2, 8, 5.

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.

Mark this as brainiest.

Hope it will be helpful.

Answer 2

Answer:

The electronic configurations of the two elements are nitrogen (Z = 7) 2, 5; Phosphorus (Z = 15) 2,8, 5.

Since the size of nitrogen is small as compared to phosphorus, it has a greater tendency to take up electrons. It is therefore, more electro-negative than phosphorus.
