What gas do you breath in?

Assuming we're talking about the air around us, the gas you breathe in is actually a mixture of gases. Roughly 80% of it is nitrogen gas which and a little under 20% of it is oxygen which is the part we need. About 1% of the atmosphere is neither oxygen or nitrogen and crudely speaking is "everything else that's in the air", about 0.05% is carbon dioxide and there are small amounts of xenon, helium, methane etc.
