Q-carbon
I propose that Q-Carbon is added to the list of carbon's solid states. reference — Preceding unsigned comment added by Rmorenojr (talk • contribs) 18:11, 8 December 2015 (UTC)

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

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)

change element 6 to Element Six Shinnigami0123 (talk) 13:15, 3 November 2023 (UTC)
 * Red question icon with gradient background.svg 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)
 * IS it possible to change Element 6 in the hat note to Element Six? Shinnigami0123 (talk) 14:08, 6 November 2023 (UTC)
 * @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)

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)
