Sagot :
Answer:
Electronic configuration of nitrogen: K=2 L=5
Electronic configuration of phosphorus : K = 2 L = 8 M = 5
The element nitrogen will be more electronegative because of the smaller size of its atom. nitrogen accepts electrons more easily.
Explanation:
Explanation:
- The atomic number of nitrogen is 7 , so its electronic configuration will be 2 , 5
- The atomic number of phosphorus is 15 , so its electronic configuration is 2 , 8, 5
Nitrogen is more electronegative than phosphorus.
Reason :-
From top to bottom down a group, electronegativity decreases.
Explanation :-
Number of shell increases down a group, so there is an increased distance b/w the valence electrons and nucleus, or a greater atomic radius.
Since nitrogen has a smaller atomic radius than phosphorus, the attraction of its nucleus towards the incoming electron is more than phosphorus. So , because of smaller atomic size nitrogen accepts electrons more easily.
