Answer 1

The correct statement about nitrogen (N) and phosphorus (P) is that they have the same number of valence electrons. Both nitrogen and phosphorus are in Group 15 of the periodic table, which means they each have five valence electrons.

The other statements are incorrect:

• They do not have the same number of electron shells; nitrogen has two electron shells, while phosphorus has three.
• They are not inert; nitrogen is a reactive gas, and phosphorus is also reactive.
• They are not classified as halogens; halogens are found in Group 17 of the periodic table.

So, the correct response is: They have the same number of valence electrons.
