Dinitrogen vs. Nitrogen: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 9, 2023
Dinitrogen is the diatomic molecule N2, the most common form of nitrogen in the Earth's atmosphere; nitrogen refers to the chemical element with atomic number 7.

Key Differences

In chemistry, dinitrogen is often used to describe the gaseous form of the element that is used in industrial processes, such as the Haber process for producing ammonia. Nitrogen, as an element, can bond with other elements to form a vast array of compounds, from nitric acid to organic molecules like amino acids.

While dinitrogen is relatively non-reactive due to the triple bond holding the two nitrogen atoms together, nitrogen atoms in other compounds can be highly reactive. For example, nitrogen in ammonia (NH3) can form bonds with acids to create ammonium salts.

Dinitrogen's stability makes it a significant part of the Earth's atmosphere, where it plays a role in buffering changes in the atmosphere and is involved in processes such as the nitrogen cycle. Nitrogen in other forms is essential for life, as it is a key component of amino acids, which are the building blocks of proteins.

The isolation of nitrogen in its pure form from dinitrogen in the atmosphere was a significant achievement in chemistry. Nitrogen in its pure form is used in a variety of applications, including the creation of inert atmospheres for the preservation of food and the manufacture of electronics.

Nitrogen

A nonmetallic element that constitutes nearly four-fifths of the air by volume, occurring as a colorless, odorless, almost inert diatomic gas, N2, in various minerals and in all proteins and used in a wide variety of applications, including manufacture of ammonia, nitric acid, TNT, and fertilizers, and as a cryogen. Atomic number 7; atomic weight 14.0067; melting point -210.00°C; boiling point -195.80°C; valence 2, 3, 4, 5. See Periodic Table.

Nitrogen

A colorless nonmetallic element of atomic number 7, tasteless and odorless, comprising four fifths of the atmosphere by volume in the form of molecular nitrogen (N2). It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, such as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14.007. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva, and boils at -195.8 ° C at atmospheric pressure. Liquid nitrogen is used as a refrigerant to store delicate materials, such as bacteria, cells, and other biological materials.
