The correct statement is:
**They have valence electrons in the same energy level.**
Nitrogen and oxygen are both in Period 2 of the periodic table, which means they have their valence electrons in the second energy level (n=2). However, they do not have the same number of valence electrons, as nitrogen has 5 valence electrons and oxygen has 6.
