Nitrogen notes

Nitrogen is atomic number 7 with the symbol N

Nitrogen has 7 electrons, 7 protons and 7 neutrons

Nitrogen is a gas at standard temperatures and pressures

Nitrogen's melting point is -210 degrees celcius
And nitrogen's boiling point is -195.795 degrees celcius

Nitrogen has one of the highest electronegativities among the elements.

Nitrogen occurs in all organisms.
Primarily in amino acids, in the nucleic acids and in the energy transfer molecule adenosine
triphosphate.

At standard temperatures and pressures,
two atoms of the element bind to form dinitrogen.

Nitrogen has two stable isotopes:
14N and 15N. Of which 14N is much more common, being more then 99 percent of natural  nitrogen.

Phases and forms:
-Normal gas nitrogen at standard room temperatures and pressures
-Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature
-Solid nitrogen is the solid form of the element nitrogen

Production:
-Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air,
or by mechanical means using gaseous air.

Uses:
-Synthetically produced nitrates are key industrial fertilisers.
-Nitrogen is a constituent of every major pharmacological drug class.
-Nitrogen is used in incandescent light bulbs as an inexpensive alternative to argon.
-Nitrogen fire suppression systems.
-Nitrogen is used in the manufacturing of stainless steel.
-Nitrogen is used in the case hardening of steel by nitriding.
-Nitrogen is used in some aircraft fuel systems to reduce fire hazard.
-Nitrogen is used to inflate race car and aircraft tires.
Liquid nitrogen uses:
-The main use of liquid nitrogen is as a refrigerant.
-Nitrogen is used in the cryopreservation of blood, reproductive cells.
