There is a request, submitted by AnonymousContibutor777 (talk), for an audio version of this article to be created. For further information, see WikiProject Spoken Wikipedia.

The rationale behind the request is: "Why not have a spoken article about carbon? We're based on it.".

Carbon has been listed as one of the Natural sciences good articles under the good article criteria. If you can improve it further, please do so. If it no longer meets these criteria, you can reassess it.

Carbon

Carbon atoms comprise a nucleus of neutrons and six protons surrounded by six electrons. Quantum mechanics dictates that the first two electrons occupy the inner atomic orbital, while the remaining four electrons have wavefunctions that only half-fill the second standard and three second principal orbitals. Demon Beast (talk) 13:00, 12 February 2023 (UTC)[reply]

@Demon Beast The article already says that carbon's electron configuration is 1s²2s²2p². Do you have a suggestion for improvement? Mike Turnbull (talk) 14:19, 12 February 2023 (UTC)[reply]

I came here to say that. The box on the right says "[He] 2s² 2p²", and in article it's 2s² 2p² 2p². Is it a mistake? Gratecznik (talk) 12:51, 16 February 2023 (UTC)[reply]

FYI: {{Infobox carbon}} reads its elconfig data here: {{Infobox element/symbol-to-electron-configuration}} (=to edit the Infobox). The article's is in-text. DePiep (talk) 13:11, 16 February 2023 (UTC)[reply]

[He] = 1s² (see noble gas notation). Double sharp (talk) 13:12, 16 February 2023 (UTC)[reply]

allotropes

Currently, there is a molecular picture of eight allotropes. It could be more informative if there would be also photos of those (as how they look like to the naked eye). 86.115.91.152 (talk) 13:24, 13 September 2023 (UTC)[reply]

change element 6 to Element Six Shinnigami0123 (talk) 13:15, 3 November 2023 (UTC)[reply]

Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. The only place Element 6 is mentioned is in the hat note. please clarify your edit request. RudolfRed (talk) 19:25, 3 November 2023 (UTC)[reply]

IS it possible to change Element 6 in the hat note to Element Six? Shinnigami0123 (talk) 14:08, 6 November 2023 (UTC)[reply]

@Shinnigami0123 The problem is that we have another article titled Element Six, for a company, while the hatnote is pointing out that Element 6 is a redirect to carbon. In fact, if you look at any article about elements, we tend to use the atomic number as digit(s) in the first sentence of the article. This is an exception to the common style of expressing numbers from 1 to 10 as words but is done for consistency. Mike Turnbull (talk) 14:47, 6 November 2023 (UTC)[reply]

Semi-protected edit request on 17 May 2024

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

Half-life mentioned in the "Isotopes" section should be changed from 5730 years to 5700 years.

Reasoning: 5730 years is a historical value, with new sources indicating 5700 years, instead. The value of 5700 years can also be found in the list of isotopes in the InfoBox on the top of this page. Valentyn235 (talk) 08:33, 17 May 2024 (UTC)[reply]

Not done: please provide reliable sources that support the change you want to be made. Charliehdb (talk) 09:37, 17 May 2024 (UTC)[reply]

Done: by using NUBASE 2020 as the source. –MadeOfAtoms (talk) 10:51, 17 May 2024 (UTC)[reply]

+== allotropes ==
-[[User:Eric Kvaalen]], as a complete non-expert I'm a bit confused by the note you added to the phase diagram in the intro, and looking to improve it. Firstly, the link referenced seems to be about the melting point of diamond ("shock-compressed" diamond, whatever that really means), which does not include the melting point of Graphite listed in the table, so this needs to be clarified. Second, is the note saying the upper line between Diamond and Liquid is wrong and should be edited? Is there a pressure-temp phase diagram from the paper that we could include here instead?

-Finally, would it be better to include this note in the text, rather than in the figure?

+== Semi-protected edit request on 3 November 2023 ==
-:{{Ping|Cstanford.math}} Hello. Yes, the title of the reference is "Melting temperature of diamond at ultrahigh pressure", because it's looking at the melting point at high pressures where the solid would be diamond. "Shock-compressed" means that they shoot a laser at a small disk of diamond, or actually at a thin coat of aluminum if I remember right on the small disk of diamond, and this causes very rapid ablation of the aluminum, which acts like a rocket engine you could say, causing a shock wave to travel through the carbon. This shock wave causes the carbon to go very briefly to very high temperatures and pressures, and they can actually figure out what the path through T-P space is. I don't know what table you are referring to. It's true that the melting point of diamond (which depends on pressure) is not the same as the melting point of graphite (which also depends on pressure), except at the "triple point" where graphite, diamond, and liquid carbon are all in equilibrium. Yes, the graph is wrong at the upper right. Instead of continuing to curve to the right, it should curve upwards toward higher pressure without ever surpassing 9000&nbsp;K in temperature. Yes, there is a diagram in the paper, but of course somebody would have to make a copy as an SVG file or whatever. Fortunately the article is open-access. Yes, we could put something in the text, but I thought it was more important to modify the caption because people need to know that the curve is wrong. Anyway, people don't always read the text very carefully. [[User:Eric Kvaalen|Eric Kvaalen]] ([[User talk:Eric Kvaalen|talk]]) 09:17, 5 October 2021 (UTC)

-:: That all makes sense, thanks! I clarified the figure caption based on what you wrote here. Mainly, I wasn't sure which part of the phase diagram the caption was correcting, but I think it's clear now. Feel free to improve further.
