Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
May 30, 2024 · The boiling temperature of nitrogen is −195.8 °C (−320.4 °F), about 13 °C (−23 °F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen.
Nitrogen is cycled naturally by living organisms through the ‘nitrogen cycle’. It is taken up by green plants and algae as nitrates, and used to build up the bases needed to construct DNA, RNA and all amino acids.
Nitrogen Uses and Properties - Nitrogen is a diatomic gas with atomic number 7 and symbol N. Know the nitrogen atomic number, the atomic mass of nitrogen and atomic weight of nitrogen. Explore the Uses of Nitrogen.
Sep 28, 2017 · Named after the Greek word nitron, for "native soda," and genes for "forming," nitrogen is the fifth most abundant element in the universe. Nitrogen gas constitutes 78 percent of Earth's...
May 30, 2024 · Nitrogen - Properties, Reactions, Compounds: Nitrogen is a colourless, odourless gas, which condenses at −195.8 °C to a colourless, mobile liquid. The element exists as N2 molecules, represented as :N:::N:, for which the bond energy of 226 kilocalories per mole is exceeded only by that of carbon monoxide, 256 kilocalories per mole.
Nitrogen is a colorless odorless gas at normal temperature. It is normally attached to another nitrogen atom, making a nitrogen molecule (N 2 ). This bond is very strong.
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.
Definition, mass & chemical names. Nitrogen. 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.
This article explores how nitrogen becomes available to organisms and what changes in nitrogen levels as a result of human activity means to local and global ecosystems.
