I think water, oxygen, sun
Ummmm yikes now thats confusing....
3 atoms (O3) Ozone is the triatomic form of oxygen. Oxygen isn’t the only thing we breathe, we also breathe nitrogen and a whole bunch of other gases. The difference between oxygen and ozone is ozone is o3 meaning it has 3 oxygen atoms instead of just one. I really hope this helped!
