What is the percentage of oxygen and nitrogen in the air we breathe?
21 percent
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
In which gaseous form does nitrogen make up 78 of the Earth’s atmosphere?
Nitrogen is the most abundant gas in the atmosphere. Air is composed of 78 percent nitrogen. Oxygen accounts for 21 percent, and the inert noble gas argon makes up 0.9 percent of the air. The remaining 0.1 percent consists of several trace gases.
Are we breathing nitrogen?
Because 78 percent of the air we breathe is nitrogen gas, many people assume that nitrogen is not harmful. However, nitrogen is safe to breathe only when mixed with the appropriate amount of oxygen. These two gases cannot be detected by the sense of smell.

What are the ingredients in the air we breathe?
What Are the Ingredients in the Air We Breathe? The air humans breathe is made up of about 78 percent nitrogen, 21 percent oxygen, and 1 percent carbon dioxide and argon. Trace gases include krypton, methane, neon, helium and hydrogen.
Which is the most abundant gas in the air?
The majority of the air we breathe is made up of nitrogen and oxygen, though you’ll also find argon, carbon dioxide and other gases in trace amounts. Nitrogen: Abundant and Inert It’s a common misconception that oxygen is the most abundant gas in the air breathed on Earth; that honor goes to nitrogen, which makes up 78 percent of the air.
