![]() | Oxidation state was nominated as a Natural sciences good article, but it did not meet the good article criteria at the time (April 26, 2021). There are suggestions on the review page for improving the article. If you can improve it, please do; it may then be renominated. |

Image correction
editI have added a correction to redox equation 1 which was pointed out by DIRAC66 in 2017 but which I missed until nowMcardlep (talk) 08:28, 24 May 2019 (UTC)
- @Mcardlep: thanks! I don't see which old discussion it is, but I assume the relevant change is O.S. on the carboxyl carbon in the product? If so, I can tweak the SVG. DMacks (talk) 12:01, 24 May 2019 (UTC)
- Yes, thanks for fixing this image. I also cannot find what you say is my previous comment, but I note now that the real problem with the previous version is that the supposed acetic acid was missing an oxygen, so we were showing the oxidation of acetaldehyde to ... acetaldehyde!??? Of course this incorrect equation was unbalanced in number of oxygens as well as charge. I am glad you have the required software to fix the diagram. Dirac66 (talk) 15:21, 24 May 2019 (UTC)
- Erledigt. I didn't draw out the O–H bond because that detail is not really relevant to the point being made here (and it's a harder edit for me to make:) DMacks (talk) 12:02, 28 May 2019 (UTC)

Copernicium
editI see that in the article copernicium 0 charge is counted as an observed oxidation state, bold because it is a main one. This is not included in whatever the file that looks like File:Langmuir valence.png|700px with all the oxidation states is. Is this accurate, and if it is, how should it be added? --Ammonium121 (talk) 18:40, 22 April 2021 (UTC)
- That file stops at uranium, doesn't it? Double sharp (talk) 03:05, 26 April 2021 (UTC)
IUPAC definition
edit"Several criteria were considered for the ionic approximation:
- Extrapolation of the bond’s polarity;
- from the electronegativity difference,
- from the dipole moment, and
- from quantum‐chemical calculations of charges.
Point b may be deceptive: in CO the negative end of the dipole is C; in pyrrole the dipole vector points from N to a direction in the middle of the ring. Patrizio 93.147.230.142 (talk) 16:28, 8 January 2023 (UTC)
