Article changed over to new Wikipedia:WikiProject Elements format by David M, and Malcolm Farmer. Elementbox converted 12:08, 23 Jun 2005 by Femto (previous revision was that of 02:15, 18 Jun 2005).

This article seems to omit information about Nitrogen in the most common form we encounter it - molecular nitrogen gas (N2) in the atmosphere, molecular mass ~28 etc - confusing for people comparing gases… — Preceding unsigned comment added by (talk) 12:55, 15 October 2018 (UTC)

N2 is covered in many places in the article, for example the "Allotropes" section, and all the information about applications and precautions focuses on it (or else we should have a ridiculously long article given the great variety of N compounds). Obtaining properties like molecular mass from those given in the infobox is at most a matter of simple calculation (the kind that should have been taught in beginning chemistry classes).

Information Sources[edit]

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Nitrogen. Additional text was taken directly from USGS Nitrogen Statistics and Information,USGS Periodic Table - Nitrogen, from the Elements database 20001107 (via, Webster's Revised Unabridged Dictionary (1913) (via and WordNet (r) 1.7 (via Data for the table was obtained from the sources listed on the main page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

Cryogenic History[edit]

It is worh mentioning that Nitrogen was first liquified in 1883 by Wrobleski and Olzewski. (Taken from "Cryogenic Technology" edited by Robert W. Vance, published by John Wiley & sons inc. 1963)


Scheele discovered nitrogen in the same year as Rutherford.

New finding about Nitrogen[edit]

Accodirding to this article [1] Nitrogen is found in metallic fluid in the Earth's core. — Preceding unsigned comment added by (talk) 13:56, 10 July 2018 (UTC)

Can some one please help with this edit[edit]

I was looking up the density for Nitrogen in the side table and noticed that the referenced website page no longer exists. the website itself doenst seem to be a reliable sources anyways. I can not figure out how to edit the this side bar....

Can some one please help me change update the density to 1.2506 kg/m^3 (at STP). kg/m^3 is easier to work with than g/L, also the cited website is a widely accepted source for engineers like myself:

also the critical point it wrong. Here is the link to the wiki's critical point page:

I have other journal papers that also cite the critical point, but I have special access to them so...

@SuperSonicFlow: I have made the changes (there's also a more accurate critical point given at Critical points of the elements (data page), so I used that one instead). Double sharp (talk) 15:21, 27 January 2019 (UTC)

Double sharp Thanks, i kept referencing for my project and was driving me nuts why my code was adding up! SuperSonicFlow (talk) 19:20, 27 January 2019 (UTC)SuperSonicFlow
