80% nitrogen, 20% oxygen
however it's really 79% plus some decimals of nitrogen and 21% oxygen and a little moisture.
But if the question is only looking for a basic answer, just use the top answer.
Nitrogen is an inert gas it maintains a proper ratio of oxygen requred by living organisms if oxygen is in higher ratio the respiratory organs become oxidized and more oxygen in blood is harmful as low concentration of oxygen.
Argon, Carbon Dioxide, Nitrogen, oxygen, hydrogen
1:4
oxygen is used by human and animals for respiration bt nitrogen do not. for consuming nitrogen plants need nitrogen fixation ths occurs on low scale on other hand oxygen is directly used so its cunsumbtion is more then nitrogen. another important point is that oxygen is used in burning, formation of water etc ths means ratio of cunsumbtion of oxygen is mor then nitrogen
Air
In the atmosphere, dry air contains 78.09% nitrogen and 20.95% oxygen by volume. Thus the ratio of nitrogen to oxygen is about 3.7:1.
The ratio is approx 268 to 1000.
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
It already is. Air is about 4/5ths nitrogen and about 1/5th oxygen (and about 1% "other stuff"). The current ratio of nitrogen to oxygen in air is about 4:1 as you can see.
No, the ratio of nitrogen to oxygen is not changed by altitude.

If the 80 and 20 you refer to in your question are percentages then the ratio would be 4:1.

Air is approximately 80% Nitrogen, 19% oxygen and 1% others
