== my June 2009 edits to CHON == |
|||
I apologize for having edited this article several times on June 29 instead of just once. It may be clear I'm newish at editing. |
|||
Both of the references were "dead links" on that date (6/19/09), and two of the three "external links" were also "dead links". |
|||
One fact (26 elements) needs verification, whether from an external source or an in-Wiki source. |
|||
Another fact (99% of all living systems) needs clarification; it's vague, as is, and unclear what meaning was intended. |

|||
== Article name == |
|||
It is not clear to me that the current article name [[CHON]] is the correct or best one. Recent news announced by NASA about [[GFAJ-1]] and [[Arsenic DNA]] have introduced me to the term [[CHNOPS]] many times. As of today (2010-12-09T14:05:10), someone has created a redirect page for CHNOPS to redir to this article. But since CHON is unsourced, it may be the case that CHNOPS is a better article name than CHON. Interested in what others think. [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 18:31, 9 December 2010 (UTC) |
|||
:Let me add that it could be the case that CHNOPS are the six most important biologically important elements and that the four CHON elements are more/most important from an astro-resource point of view. I don't know, of course, because there are no citations for the CHON claims. So ultimately, the CHON stuff might just fall out of the article completely if it doesn't get sourced. |
|||
:However, if the CHON stuff gets sourced and stays in the article, it does suggest a better organizational schema for the sections might include something like: |
|||
:*CHNOPS—biologically important, |
|||
:*CHON—astrochemically important, |
|||
:no matter what we decide is the best name for the article.[[User:N2e|N2e]] ([[User talk:N2e|talk]]) 06:12, 12 December 2010 (UTC) |
|||
::I just located a citation for CHON, and have added it to the article. Thus, it is no longer totally unsourced. This makes me think that maybe CHON and CHNOPS ought to be separate, albeit related articles. Thoughts? [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:47, 7 January 2011 (UTC) |
|||
==Proposed article split== |
|||
Per the logic of the discussion above, I am proposing to split this article into two articles: |
|||
:*CHNOPS—biologically important—per current science, of critical importance to all [[biological life]]. Currently of interest, per tag on this article, to the {{tl|WikiProject Biology}} project. The {{tl|WikiProject Chemistry}} project would likely be interested in both articles. |
|||
:*CHON—astrochemically important—important for extraterrestrial resource [[mining|extraction]] for off-Earth construction, rocket fuel production, etc. Widely used in Science Fiction space genre for many years. Likely of interest to {{tl|WikiProject Spaceflight}} and perhaps other WikiProjects. |
|||
I don't think it is straightforward to keep them together, and conflate their use as the article does a bit of today, when the terms are typically used by entirely different communities (with the exception of the astrobiologists, who would likely be familiar with both). The sources seem to indicate this distinction, as do Google searches on the terms. Cheers. [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 19:04, 12 January 2011 (UTC) |

===Comments on the split, with no support or oppose=== |
|||
*If you look at article history, you will note that the unsourced claims about ''CHON'' are gradually being deleted from the article. This is fine, and consistent with [[WP:V]]. However, it does appear that there may, in the end, be very little ''CHON'' material left for a second/splt article, and that references to ''CHON'' may eventually fall out completely from this article, as unrelated to the material that is sourced on CHNOPS. NET: now would be a really good time for interested CHONians to find sources to support the CHON claims remaining in this article.

== Not what I'm looking for. == |

I was looking for "CHON" as a molecular formula, containing the following: |
|||
H-N=C=O |
|||
Where there is one hydrogen, nitrogen, carbon, and oxygen atom. The hydrogen bonds to the nitrogen. The nitrogen has a double bond with the carbon. The carbon also has a double bond with the oxygen.

== CHON claims remain almost totally unsourced == |
|||
{{asof|2011|08}}, the CHON claims in the article are nearly totally unsupported. I was able to find one CHON source that I added to the article back in January 2011. If the unsourced claims are not supported, I will soon remove each of the unsourced CHON-related claims. (And if so, it would probably be appropriate to just [[WP:MOVE]] the article to CHNOPS and thereby change the article name from CHON to CHNOPS.

:Whatever may be the merits of [[CHON]] as astro''biological''ly important in science fiction, it appears no editor ever located any sources for the unverified claims, despite being fact-tagged for the past three months.

|||

Both of the references were "dead links" on that date (6/19/09), and two of the three "external links" were also "dead links".

Wiki Education assignment: ASTBIO 502 Astrobiology Special Topics -Origin Of Life
This article was the subject of a Wiki Education Foundation-supported course assignment, between 30 September 2023 and 8 December 2023. Further details are available on the course page. Student editor(s): MikeSadler11 (article contribs). Peer reviewers: Plutooprojector.

Merge proposal: Merge from CHON
I propose merging CHON into CHNOPS because of closely related and overlapped content, small size of CHON, and ease with which they can both be covered and distinguished. See old related discussions at: Talk:CHON § Article name, Talk:CHON § Proposed article split and Talk:CHON § Name change proposal. –MadeOfAtoms (talk) 22:58, 9 December 2023 (UTC)
- Support Seems to be identical content. scope_creepTalk 07:38, 10 December 2023 (UTC)
- Support the merge. The key thing we should not lose in the merge is the CHON is also a common acronym for the most important elements (may be even more common in the literature that CHNOPS), and that CHON make up 96% of the mass in biological systems, and that CHON materials are rather common in carbonaceous asteroids. Probably, CHON can just be in a separate section of the CHNOPS article, and CHON should clearly redirect there. In reality CHON is the big stuff in bio systems, with P & S critical, but each <1% by mass; then the many many other elements that are critical to life probably just follow a power-law distribution downwards; elements that are small in terms of mass or percentage, but life doesn't work without them. N2e (talk) 00:44, 11 December 2023 (UTC)
I Withdraw this merge proposal pending some study of the present contents of CHNOPS. The quality is so poor that I would not be willing to attempt to salvage it. It has the character of an article written mostly or entirely by an AI chatbot, in my opinion. My apologies for the false start. –MadeOfAtoms (talk) 23:56, 12 December 2023 (UTC)
- Thank you User:MadeOfAtoms and User:Drmies for taking the time to look at those edits. I now understand that the way I moved the material was incorrect, for that I apologize. I was editing this apge as part of a course I was taking on the Origins of life (abiogenesis, homochirality, polymerization, proto cells, RNA world, rhibozymes, phylogeny, LUCA.. etc). all students were to select and improve a relevant page. I had hoped to create a new CHNOPS page, moving my sandbox to it, but learned that one already existed (but it had no content), but being redirected to the CHON page. In my haste to get the title to what I thought was more relevant I made those errors. Considering that the CHON page hadn't seen much activity in several years, I thought it would be fine, and that version control would save the version and revision history of the CHON page.
- Thank you for agreeing and making the CHON move to CHNOPS after reverting to the old version, I agree that CHNOPS is a more relevant title for the content and that perhaps a subsection for CHON (composing >96% by mass) is deserving. However, no matter how little phosphorus and sulfur compose life by mass, it phosphorus and sulfur are also essential so I don't think they should be left out.
- I'm sorry that you think it was written by a chatbot (it wasn't), I do hope you had the time to read through those references. Furthermore, I thought that the additional details/sections and reorganization would provide clarity to the content while also providing more structure for future edits by the wiki community.
- Thank you to User:LambdaWolf and User:DI2000 for making some comments and edits before the page was reverted back. I had included the initial summary and scope clarification for a quick read, and to differentiate it from CHON or specific element information. However, if you and others didn't think it was valuable than I'm okay with that too.
- User:MadeOfAtoms was there any specific content which you disagreed with or found to be incorrect? were there sections that you thought the old content was better in either content or format?
- I will not be re-editing this page until there is a general consensus. Again, my apologies for making the move incorrectly, thank you for pointing out and fixing that error.
- MikeSadler11 (talk) 01:41, 13 December 2023 (UTC)
- @Scope creep @Drmies can we merge the talk pages? This is really confusing that we seem to have switched talk pages. I do not know what happened here. Immanuelle ❤️💚💙 (talk to the cutest Wikipedian) 02:21, 13 December 2023 (UTC)
