== 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.

I propose that Q-Carbon is added to the list of carbon's solid states.

== 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?


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). [[Special:Contributions/86.115.91.152|86.115.91.152]] ([[User talk:86.115.91.152|talk]]) 13:24, 13 September 2023 (UTC)
Finally, would it be better to include this note in the text, rather than in the figure?
Thanks! [[User:Cstanford.math|Cstanford.math]] ([[User talk:Cstanford.math|talk]]) 12:49, 4 October 2021 (UTC)


== 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.

Carbon

[edit]

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]
