Nitrogen
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.
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.
Oxygen is the most abundant element on Earth. It comprises 49.5 percent of the total mass (amount) of the Earth's crust, waters, and atmosphere.
The two Earth regions where oxygen is the second most abundant element by volume are the Earth's crust, after silicon, and the Earth's atmosphere, after nitrogen.
The most abundant element where? It is the most abundant element in Earth's crust. The most abundant element on planet Earth, on the other hand, is iron, while the most abundant element in the Universe is hydrogen.
Nitrogen is the most abundant element in the earth's atmosphere.

Hydrogen is the most abundant element in the universe, but it is relatively rare in the Earth's atmosphere. It makes up only about 0.000055% of the atmosphere by volume.

The most abundant element in Jupiter's atmosphere is hydrogen, making up around 90% of its composition. Helium is the next most abundant, followed by smaller amounts of methane, ammonia, and water vapor.
