The correct statement about nitrogen (N) and phosphorus (P) is:
**They have the same number of valence electrons.**
Nitrogen (atomic number 7) and phosphorus (atomic number 15) both have 5 valence electrons, as they are in the same group (group 15) of the periodic table.
The other statements are incorrect:
- They are not inert; nitrogen can react under certain conditions, and phosphorus is highly reactive.
- They are not classified as halogens; halogens are found in group 17 of the periodic table.
- They do not have the same number of electron shells; nitrogen has 2 electron shells, while phosphorus has 3.
