Nitrogen is a chemical element with symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772.

Nitrogen is a chemical element with symbol N and atomic number 7. Classified as a nonmetal, Nitrogen is a gas at room temperature. J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205. DOI:10.1063/1.1725697. B. Cordero, V. Gómez, A.E. Platero-Prats, M. Revés, J. Echeverría, E. Cremades, F. Barragán, S. Alvarez, Dalton Trans. 2008, 21, 2832-2838.

Where the element is most commonly found in nature, and how it is sourced commercially. The wheat sheaf symbol and lightning reflect the importance of nitrogen to living things. Nitrogen is important for plant growth and can be ‘fixed’ by lightning or added to soils in fertilisers. Nitrogen is important to the chemical industry.

Nitrogen (pronounced as Nye-treh-gen) is a chemical element, existing in the form of a colorless diatomic gas. Denoted by the chemical symbol N, it belongs to the family of nonmetals. It is the fifth most abundant element in the earth’s crust, represented by the molecular formula N 2 [1, 2].

Nitrogen is the 7th element in the periodic table and has a symbol of N and atomic number of 7. It has an atomic weight of 14.007 and a mass number of 14. Nitrogen has seven protons and seven neutrons in its nucleus, and seven electrons in two shells. It is located in group fifteen, period two and block p of the periodic table.

In 1790 the French chemist Jean-Antoine-Claude Chaptal named the element ‘nitrogen’ after experiments showed it to be a constituent of nitre, as potassium nitrate was called then. About 2.5 percent of the weight of living organisms comes from nitrogen in organic molecules. Many of the molecules of life contain nitrogen.

nitrogen, Gaseous chemical element, chemical symbol N, atomic number 7. A colourless, odourless, tasteless gas, it makes up 78% of Earth’s atmosphere and is a constituent of all living matter. As the nearly unreactive diatomic molecule N 2, it is useful as an inert atmosphere or to dilute other gases.
