$NO_2$ and $NO_3$

Work Step by Step

To find the number of valence electrons, multiply the number of valence electrons of each element by the number of that element in the molecule. Recall, Oxygen has 6 valence electrons, and Nitrogen has 5 valence electrons. In addition, Hydrogen has one valence electron, Sulfur has 6, and Chlorine has 7. Using this information, we find that $NO_2$ and $NO_3$ are the only ones with an odd number of valence electrons.
