Why nitrogen is important for life?
Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.
How is nitrogen made naturally?
When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen (e.g. amino acids, DNA). Various fungi and prokaryotes then decompose the tissue and release inorganic nitrogen back into the ecosystem as ammonia in the process known as ammonification.

Can you breathe nitrogen?
Nitrogen is an inert gas — meaning it doesn't chemically react with other gases — and it isn't toxic. But breathing pure nitrogen is deadly. That's because the gas displaces oxygen in the lungs. Unconsciousness can occur within one or two breaths, according to the U.S. Chemical Safety and Hazard Investigation Board.
Where did the word nitrogen come from?
The English word nitrogen (1794) entered the language from the French nitrogène, coined in 1790 by French chemist Jean-Antoine Chaptal (1756–1832), from the French nitre ( potassium nitrate, also called saltpeter) and the French suffix -gène, "producing", from the Greek -γενής (-genes, "begotten").

How is nitrogen gas produced?
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption ). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen for steelmaking and other purposes. When supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen). Commercial-grade nitrogen already contains at most 20 ppm oxygen, and specially purified grades containing at most 2 ppm oxygen and 10 ppm argon are also available.

How does nitrogen travel?
So, nitrogen in the air is ‘fixed’ by bacteria or by lightning, turning it into nitrate or ammonium compounds in water or soils, which are used by plants to grow. The plants are then eaten by animals. Nitrogen is returned to the soil through dead animal or plant matter, and the cycle continues.
Why is nitrogen important for life?
Plant, animals, and humans would not be able to live without nitrogen, but the nitrogen in the air is unusable, it needs to be chemically bonded with other elements to form useful compounds for life. Important molecules like amino acids, proteins, and nucleic acids (e.g. DNA) all contain nitrogen. We obtain most of our nitrogen from eating plants and animals, but they are only able to obtain the element from either nitrate (NO3-) or ammonium (NH4+) compounds.
How does nitrogen help plants grow?
Human beings have discovered the importance of nitrogen in growing plants, and so add to the nitrogen cycle by fixing nitrogen industrially, by means of the Haber Process, which turns nitrogen from the air into ammonia which is then used to make nitrogen fertilizers, encouraging plants to grow stronger and faster. Unfortunately, overuse of nitrate fertilizers can have a detrimental effect on the environment, through entry into groundwater and drinking water, which can cause health problems, especially to new-born babies.
What are the two most abundant gases in the atmosphere?
Nitrogen and oxygen are the two most abundant gases in the air. Oxygen makes up about 21 percent and nitrogen, about 78 percent, leaving just one percent to be shared between carbon dioxide, the noble gases, and other gases. Oxygen is reactive and is involved in many reactions, in fact, it is the constituent of the atmosphere that makes the earth habitable by living creatures. Nitrogen, on the other hand, is very unreactive as the gas that we find in the atmosphere.
Can living things live in nitrogen?
Living things cannot live in pure nitrogen , and neither can combustible materials burn in it. These facts lead to the use of nitrogen to provide a non-reacting atmosphere for welding, glass-making, and other processes where oxidation would be a problem in normal air. The gas is also used for flushing out oil pipelines and tanks to remove flammable or explosive vapor, for food packaging to prevent food from being spoiled by reaction with oxygen, and in corn silos to prevent dust explosions.

Alchemists knew nitric acid as aqua fortis (strong water), as well as other nitrogen compounds such as ammonium salts and nitrate salts. The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve
Properties
A nitrogen atom has seven electrons. In the ground state, they are arranged in the electron configuration 1s 2s 2p x2p y2p z. It therefore has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons) are unpaired. It has one of the highest electronegativities among the elements (3.04 on the Pauling scale), exceeded only by chlorine (3.16), oxygen (3.44), and fluorine (3.98…

The gas is mostly used as an inert atmosphere whenever the oxygen in the air …
Safety
Although nitrogen is non-toxic, when released into an enclosed space it can displace oxygen, and therefore presents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively poor and slow low-oxygen (hypoxia) sensing system. An example occurred shortly before the launch of the first Space Shuttle mission on March 19, 1981, when two technicians died from asphyxiation after they walked into a space located in the Spac…
