CAS 7727-37-9 Pure Nitrogen Gas / Nitrogen N2 Gas As A Modified

Description:

Nitrogen is the lightest pnictogen and at room temperature, it is a transparent, odorless diatomic gas.

Nitrogen is a common element in the universe, and is considered the seventh most abundant chemical element by mass in the universe, the Milky Way, and the Solar System. According to physical cosmology theory, it was originally created by fusion processes from carbon and hydrogen in supernovas.[39]Molecular nitrogen and nitrogen compounds have been detected in interstellar space by astronomers using the Far Ultraviolet Spectroscopic Explorer.

Due to the volatility of elemental nitrogen and its common compounds with hydrogen and oxygen, nitrogen was driven out of the planetesimals in the early Solar System by the heat of the Sun and lost to the rocky planets of the inner Solar System. Nitrogen is consequently a relatively rare element on these inner planets, including Earth. Neon, which occurs in equal abundance in the universe, is rare in the inner Solar System for the same reason. Nitrogen is estimated at 31st element in crustal abundance. Nitrogen also occurs in some relatively uncommon minerals, such as saltpeter, Chile saltpeter and ammonium chloride. Because of the ready solubility of naturally-occurring nitrogen compounds, these minerals were concentrated from the crust by the leaching of rivers and collected in ancient seas which then evaporated, leaving the deposits of present day. A similar process occurred with the water-soluble compounds of the uncommon light elementboron.

Nitrogen and its compounds occur far more commonly as gases in the atmospheres of planets and moons that are large enough to have atmospheres. Molecular nitrogen is a major constituent of not only Earth's atmosphere, but also the Saturnian moon Titan's thick atmosphere. Also, held by gravity at colder temperatures, nitrogen and its compounds occur in variable amounts in the planetary atmospheres of the gas giant planets.

Nitrogen is present in all known living organisms, in proteins, nucleic acids, and other molecules. It typically makes up around 4% of the dry weight of plant matter, and around 3% of the weight of the human body. It is a large component of animal waste, usually in the form of urea,uric acid, ammonium compounds, and derivatives of these nitrogenous products, which are essentialnutrients for all plants that cannot fix atmospheric nitrogen.
