Hello fellow Wikipedians,

The molecular orbital diagram here in the allotropes section([ [1]]) is quite different from the one for the same molecule given here([ [2]]. The bonding 2p pi orbitals are lower in energy compared to the bonding 2p sigma orbital as per the latter while the one in this article shows the opposite picture. As my understanding of molecular orbital theory is quite limited, i am not sure which one is correct. Although what i have learnt till now tells me that the latter is correct, i think it would be best to let someone with a better understanding of the theory to have a look and suggest an edit... — Preceding unsigned comment added by 175.100.159.88 ( talk) 04:45, 20 March 2018 (UTC)
Accodirding to this article [3] Nitrogen is found in metallic fluid in the Earth's core. — Preceding unsigned comment added by 201.234.55.22 ( talk) 13:56, 10 July 2018 (UTC)
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 78.147.47.6 ( talk) 12:55, 15 October 2018 (UTC)
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 dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). 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.
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:
https://www.engineeringtoolbox.com/gas-density-d_158.html
also the critical point it wrong. Here is the link to the wiki's critical point page:
/info/en/?search=Critical_point_(thermodynamics)
I have other journal papers that also cite the critical point, but I have special access to them so...

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
Greenwood and Earnshaw give 8 N atoms. Apparently now it is 11. However I guess the exact figure and exact compound does not really matter since (1) it is all small potatoes compared to thousands of carbon atoms and (2) something that G&E devote literally one line to is probably not worth including. So I deleted the exact number and compound.
As for electron affinity; while this was initially mentioned, it was not cited, so I removed it. It is a real thing, I would not object to its return with a citation, but it should perhaps be noted that G&E make no bones about it being negative for N, which makes me wary about its actual importance. Just from the UK high school syllabus you can see electron affinity becomes important for calculations when you are trying to make an ionic compound only, and in that case it doesn't really matter that it goes a bit negative (never mind qualms about whether they really are significantly negative in reliable sources) because the lattice energy will overcome it. The second electron affinity for oxygen and sulfur is also negative, but that never stopped ionic oxides and sulfides from existing. Double sharp ( talk) 04:41, 23 August 2020 (UTC)
In this article, the author mention about the very unstable existence of +6 oxidation state of nitrogen but didn't cite them and I couldn't find any articles about it. Can anyone help me cite them? Ilys6 ( talk) 06:31, 20 July 2021 (UTC)
The density is given at STP ( Standard Temperature and Pressure), which is defined as 0°C and 100.0 kPa since 1982. However, the note next to the density N2 specification ("0°C and 1013 mbar") seems to loosely imply that the pre-1982 definition of STP is used. The density value refers to The Engineering Toolbox, which explicitly uses the pre-1982 STP definition. The value of the N2 density specified on the Wikipedia page does indeed seem to pertain to the pre-1982 STP definition. Using the current STP definition, the correct value would therefore be closer 1.249, but I don't know the exact value.
I would suggest to convert the density number to conform with the post-1982 STP definition, and change the reference to read "derived from The Engineering Toolbox" or similar.

It is worth mentioning that Nitrogen was first liquefied 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.
It won't let me edit the page but someone with privileges to edit it might want to just have it say "Pluto" instead of "the planet Pluto". No need to have anything unnecessarily argumentative put into it. Whether you think it should count as a planet or not, you should be fine with it just being referred to as Pluto. This is in the image on Pluto to the right of the section on solid nitrogen.
