The correct statement is:
**They have the same number of valence electrons.**
Nitrogen (N) has 5 valence electrons, and Oxygen (O) has 6 valence electrons, so they do not have the same number of valence electrons.
Now let's analyze the other choices:
- **They have valence electrons in different energy levels.** This is incorrect; nitrogen and oxygen are in the same period (Period 2), which means their valence electrons are in the same energy level (n=2).
- **They have valence electrons in the same energy level.** This statement is true; both elements have their valence electrons in the second energy level (n=2).
- **They have the same number of electrons.** This is incorrect; nitrogen has 7 electrons, and oxygen has 8 electrons.
Therefore, the most accurate statement regarding nitrogen and oxygen in the context of their valence electrons is:
**They have valence electrons in the same energy level.** (which could have been another option).
