Nitrogen(atomic number 7 ) and phosphorus (atomic number 15) belong to group 15 of the periodic table. Write the electronic configurationos these two elements.Which of these will more electronegative? Why?

Text Solution

Verified by Experts

The electronic configuration of Nitrogen = 2 5.
The electronic configuration of phosphorus = 2 8 5
As in their outermost shells, there are five electrons, therefore, they are non-metallic and are electronegative in nature. Nitrogen will be more electronegative because electron affinity decreases from top to bottom in a group.
