Quick question about science.
What is the most common form of Nitrogen-Oxygen compound. And if it helps, the ones formed in the sky, and the reason for the northern lights.
Please give the formula as well*.
*By formula, I mean compound formula. Aluminum and Oxygen make Aluminum Oxide… damn, I don’t know the chemical abbr. for the element… like NO2, or O2, or AlO6, or whatever.
Thanks in advance.
