The air we breathe is:
about 78% Nitrogen
about 20% Oxygen
about 1% Argon
and the rest lots of other chemicals in tiny amounts.
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
Nitrogen
The colorless, odorless and tasteless gas that you breathe in is called oxygen, the chemical symbol of which is O2. Similarly, the gas that you breathe out is called carbon dioxide.
The atmosphere is primarily composed of nitrogen followed by oxygen. The nitrogen concentration is some 78 percent by volume.
These gases are nitrogen, oxygen and argon.
Oxygen it helps the trees breathe too.
The gas you breathe in from the air is called oxygen.
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
The primary gas found in air is nitrogen, which makes up about 78% of the Earth's atmosphere. Oxygen is the second most abundant gas, comprising about 21% of the air we breathe.
Oxygen is approximately 21% of the air we breathe.
Oxygen is about 1/4 of the air that we breathe. It's a gas at ordinary temperatures and pressures.
In dry air it is argon, but under typical conditions, it is water vapor.

It is a gas.
Nitrogen which makes up about 78 percent of the atmosphere.
