Nitrogen is a colorless, gaseous element with atomic number 7 and mass number 14. It has seven protons and seven neutrons in its nucleus, and seven electrons in two shells.
The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere.

21 lis 2020 · Learn about the atomic number, mass, radius, density, electron configuration and other properties of nitrogen, a colourless, odourless unreactive gas that forms about 78% of the earth’s atmosphere. The atomic mass of nitrogen is 14.0067 u and the mass number of its typical isotopes is 14 or 15.
It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas. Nitrogen is obtained from liquefied air through a process known as fractional distillation. From the Latin word nitrum, Greek Nitron, native soda; and genes, forming.
It is considered as the 4 th most abundant element in the human body and makes about 3% by mass of the body. A specialized cycle keeps the natural balance of nitrogen between the biotic and abiotic component (atmosphere, organic compounds and biosphere) of the ecosystem in order. Nitrogen is a colorless and odorless gas.
