“Air” is the term we use for the culmination of gases that make up out atmosphere, the majority of it being nitrogen and oxygen.

Therefore “air” is simply a construct of gases, of which we can breath (using oxygen).

*molecular nitrogen and molecular oxygen, not hydrogen. Molecular (and atomic) hydrogen are extremely uncommon in the atmosphere. Water (H2O, the most abundant source of hydrogen in the atmosphere) can make up anywhere from 0-5% of the atmosphere depending on relative humidity. Otherwise, this is correct. Before we knew about gases, they called the fluid we breathe "air." Now we realize that this air is made of atoms (they didn't have atomic theory at the time, at least not well established atomic theory to say the least) in the gas phase.

Damn I meant Nitrogen. I need to stop doing this late at night. I feel like my IQ drops by 70%

No worries. That's me during the day lol. I assumed it was a typo, but for OP's sake, I thought I should mention it.

Well doing so allowed me to correct it so thanks a bunch
