Nitrogen is a chemical element with the symbol N and atomic number of 7.





Under normal conditions nitrogen is a colorless, odorless and tasteless gas.





Nitrogen makes up around 78% of the air you breathe.





Nitrogen is present in all living things, including the human body and plants.





Nitrogen gas is used in food storage to keep packaged or bulk foods fresh. It is also used in the making of electronic parts, for industrial purposes and has many other useful applications.







Nitrogen gas is often used as an alternative to carbon dioxide for storing beer in pressurized kegs. The smaller bubbles it produces is preferred for some types of beer.







Titan, the largest moon of Saturn, has an atmosphere nearly entirely made of nitrogen (over 98%). It is the only moon in our solar system known to have a dense atmosphere.
