The molecules of two different elements, nitrogen and oxygen, make up about 99 percent of the air. The rest includes small amounts of argon and carbon dioxide. (Other gases such as neon, helium, and methane are present in trace amounts.) Oxygen is the life-giving element in the air.
Moreover, what elements are in the air we breathe?
The air you breathe is made up of lots of other things besides oxygen! Oxygen only makes up about 21% of air. About 78% of the air you breathe is made up of another gas called nitrogen. There are also tiny amounts of other gases like argon, carbon dioxide and methane.
Also Know, do we breathe only oxygen?
Oxygen is used up, and the rest just remains there. A similar occurrence happens where breathing is concerned. When we inhale air, all the other gases present in it also enter our lungs. We have no selective mechanism to inhale only oxygen.
What is called Air?
Air is the general name for the mixture of gases that makes up the Earth's atmosphere. This gas is primarily nitrogen (78%), mixed with oxygen (21%), water vapor (variable), argon (0.9%), carbon dioxide (0.04%), and trace gases.
What is the importance of air?
Air is important for living things. People need to breathe, and so do lots of other animals—and plants! Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide.
