The correct statement about nitrogen (N) and phosphorus (P) among the options provided is:
**They have the same number of valence electrons.**
Both nitrogen and phosphorus are in Group 15 (V-A) of the periodic table, which means they both have 5 valence electrons.
The other statements are incorrect because:
- They are not halogens; halogens are found in Group 17 (VII-A) of the periodic table.
- They are not inert; inert gases are in Group 18 (VIII-A).
- They do not have the same number of electron shells; nitrogen has 2 electron shells (2, 5) while phosphorus has 3 electron shells (2, 8, 5).
**They have the same number of valence electrons.**
