I find it rather illogical that Airbenders can only manipulate 21% of the air around them. If we're apply real world science in this situation, Airbenders bend most of (if not all of) the air around them, which is comprised of 79% diatomic nitrogen, 21% diatomic oxygen and 1% trace gases such as argon, ozone and methane. While oxygen gas is molecular, it's only one component of the complex molecule that is air. You are correct about fire and water. Fire needs oxygen gas for a combustion reaction to take place, and water is formed from the polar covalence of oxygen gas and diatomic hydrogen.
