Nitrogen I think
what is most of the air in the atmosphere made up of
most of the air is made up of nitrogen and oxygen. But, 2% of the air is made up of other different kinds of gasses
Oxygen
Nitrogen.
air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
Most of Earth's dry air is made up of nitrogen (about 78%) and oxygen (about 21%). Other gases such as argon, carbon dioxide, and water vapor make up the remaining composition.
The majority of exhaled air in vertebrates is made up of nitrogen and oxygen, which are the primary components of air. Carbon dioxide, a waste product of cellular respiration, is also present in exhaled air in smaller amounts.
Which gas is air mostly made up from
Most of the air we breathe is made up of nitrogen (about 78%) and oxygen (about 21%). The remaining 1% is composed of other gases such as argon, carbon dioxide, and trace amounts of other gases.
Approximately 21% of the air we breathe is made up of oxygen.
Air is made up of: 78% Nitrogen 21% Oxygen1% Argon ppm levels of several other gases
99 percent of air is made up of air pollution from motor vehicles.
