it is oxygen
Nitrogen is the most common element in the air you breathe.The earth's atmosphere consist of approximately79% nitrogen, 20% oxygen, and 1% other gases.On Earth, the most common element in the air is Nitrogen.
Nitrogen
Hydrogen is the most common element in the universe, not oxygen.Oxygen is the most common element on Earth, followed by silicone.
The air (on ground level, not in a traffic jam!) is composed of ~80% N2, ~20% O2, 0-6% H2O (vary a lot), 0.03% CO2, 1% argon and then traces of other elements. The most abundant element is thus nitrogen N.
The most abundant element in the troposphere is nitrogen, making up about 78% of the atmospheric composition. Oxygen is the second most abundant element in the troposphere, making up about 21% of the atmosphere.

nitrogen helium and carbon

Nitrogen or if your talking about the crust Silicon
Several bacteria can fix the nitrogen fom atmosphere.
Water is not an element. The element that is most present in the atmosphere is Nitrogen at about 70% (Oxygen is about 20%). I don't know about the most common element in the earth's crust though. I'd say that the most common element overall is Carbon (since all life is carbon based)
Oxygen (20%) and nitrogen (80%).
