What is nitrogen meaning

nitrogen

The spray cream is foamed with the help of nitrogen.

Nitrogen is a chemical element, i.e. a certain chemical substance. It is abbreviated with the chemical symbol N. Pure nitrogen has no color, smell, and taste. It doesn't burn. Nitrogen is a gas and makes up most of our air: almost four fifths of the air is nitrogen and only about one fifth is oxygen. We would suffocate in pure nitrogen, hence the name. However, nitrogen also occurs in many chemical compounds with other substances.

Nitrogen is very important for all living things. It occurs in many nutrients, for example in protein. However, only very few, very small living things can use the nitrogen from the air, for example some bacteria. However, nitrogen compounds also occur in the soil and help the plants to grow.
