Pro Tip 1/3Common Gas
Nitrogen is invisible and non-reactive at room temperature, unlike oxygen which supports combustion.
Despite being so common, nitrogen does not burn or support fire.
Pro Tip 2/3Invisible but Crucial
Nitrogen is essential for living organisms to create proteins, although we cannot see or smell it.
Plants absorb nitrogen from the soil to grow.
Pro Tip 3/3Used in Phrases
The phrase 'nitrogen cycle' refers to the continuous movement of nitrogen in different forms in nature.
The nitrogen cycle is a key concept in understanding ecology.

So you ask, just how small are atoms? To understand this, let's ask this How many atoms are in a grapefruit? Well, let's assume that the grapefruit is made up of only nitrogen atoms, which isn't at all true, but there are nitrogen atoms in a grapefruit. To help you visualize this, let's blow up each of the atoms

I've been experimenting more and more with LN2, liquid nitrogen. I've used it in battle on 'Iron Chef America,' but have also made some great ice creams at home for my family. Since it freezes basically on contact, you can have ice cream ready in mere minutes.

Asa Gray
American Scientist
Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.

In order to 'go out the door' safely, we go through a pretty thorough process called pre-breathe. This is the process of flushing all the nitrogen out of our systems by breathing higher concentrations of oxygen.
Quote examples
Tatiana Schlossberg
Excess nitrogen from the fertilizers can cause eutrophication in the ocean, which can lead to harmful algae blooms or hypoxia - reduced levels of oxygen that create conditions in which organisms can't survive.

Robert M. Pirsig

Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?

Albrecht Kossel
German Scientist
The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.

We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.
