Nitrogen is the most abundant element in the earth's atmosphere.
Hydrogen is the most abundant element found on Earth. Other abundant elements include helium, and oxygen, as well as silicon.
The two most abundant gases in clean dry air are nitrogen, making up about 78%, and oxygen, making up about 21%.
a. Nitrogen is the most abundant element in air, making up about 78% 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.
Nitrogen is the most abundant gas in clean dry air, making up about 78% of the atmosphere. Oxygen is the second most abundant gas at around 21%, with trace amounts of other gases such as argon, carbon dioxide, and helium making up the remainder.
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
