The correct statement is: **they have the same number of valence electrons**.
Both nitrogen (N) and phosphorus (P) are in Group 15 of the periodic table and have five valence electrons. The other statements are incorrect:
- Nitrogen and phosphorus do not have the same number of electron shells (nitrogen has two electron shells, while phosphorus has three).
- Neither nitrogen nor phosphorus is classified as halogens; halogens are found in Group 17.
- They are not both inert; nitrogen can be reactive, and phosphorus is also known to react with other elements.
