What is Nitrogen as on the Periodic Table? Definition of the Nitrogen Element
Nitrogen is a gas. It is a non-metallic 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  is a constituent of all living tissues. Refer to Nitrogen Reaction for its reaction to Water, Oxygen & Acids. Nitrogen is an essential element for life, because it is a constituent of DNA and, as such, is part of the genetic code. It is used in a wide variety of important manufactures, including ammonia, nitric acid, TNT, and fertilizers. The Atomic Number of this element is 7 and the Element Symbol is N.

 

What is Nitrogen? Origin / Meaning of the name Nitrogen
The name originates from the Latin nitrum and Greek nitron for "native soda" and genes for "forming" because of nitrogen's presence in Potassium nitrate, so called salpeter or nitre or native soda.

What is Nitrogen? Periodic Table Group and Classification of the Nitrogen Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a gas. Nitrogen
is classified as an element in the 'Non-Metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium).

What is Nitrogen? Occurrence of the Nitrogen Element
Constitutes nearly four-fifths of the air by volume (78.1% by volume, 75.5% by weight)
Obtained from liquid air. Nitrogen is also an essential constituent of all living organisms; for example, the human body contains about 2.4% of nitrogen.

What is Nitrogen? Facts about the Discovery and History of the Nitrogen Element
Nitrogen was discovered by the English chemist Rutherford in 1772 who determined that the air in which animals had breathed, even after removal of the exhaled carbon dioxide, was no longer able to burn a candle. A little later Scheele showed it to be a constituent of air, and Lavoisier gave it the name azote, signifying that it would not support life. The name nitrogen was afterwards given it because of its presence in saltpeter or niter. The term azote and symbol Az are still retained by the French chemists.

Carl Wilhelm Scheele
Carl Scheele (9 December 1742 21 May 1786) was a German chemist who made a number of important chemical discoveries before many others but was rarely given the credit for his findings. For instance, although Scheele discovered oxygen Joseph Priestley published his findings first so was given the credit. Carl Scheele also identified molybdenum, Tungsten, Barium, Hydrogen and Chlorine before Humphry Davy and other scientists.

Antoine Lavoisier
Antoine Lavoisier was famous for his care in quantitative experiments, for demonstrating the true nature of combustion, for introducing system into the naming and grouping of chemical substances. Lavoisier was executed in 1794 during the French Revolution.

What is Nitrogen - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Nitrogen is just one element that can be found.
