# Talk:Rhenium

Currently, the common oxidation state of rhenium that is listed in the infobox is only +4. However, I think +7 should also be a common oxidation state, due to its mention in various textbooks (Housecroft, C. E.; Sharpe, A. G. (2012). Inorganic Chemistry (4th ed.). Prentice Hall. ISBN 978-0273742753.), and manganese and technetium both having +7. Elements lower down the column should have a greater ability to stabilize higher oxidation states.

I will implement this for now, as it gathered no opposition. Keres🌕Luna edits! 22:38, 10 December 2024 (UTC)

Isn't the melting/sublimation point of carbon also higher than rhenium's ? 174.103.211.175 (talk) 01:59, 17 January 2025 (UTC)

Well, under "Characteristics" carbon is compared to it, but noted as a case that sublimes instead of melts. Double sharp (talk) 02:01, 17 January 2025 (UTC)
The section has no sources. Johnjbarton (talk) 02:04, 17 January 2025 (UTC)

@Sand quartz added multiple subsections on the use of Rhenium in wind turbines. The content was sourced to a single primary source, cited multiple times. The source is not primarily about wind turbines or Rhenium for that matter. The source describes a study of adding Rh to Ni-Cr powder coatings. There is no evidence that the coatings were ever used on turbines. We need secondary sources to show this topic is notable. In view of the unusual multiple references to a single primary sources, please also see WP:COI. Johnjbarton (talk) 15:41, 26 February 2025 (UTC)

The opening paragraph says this:  It shows in its compounds a wide variety of oxidation states ranging from −1 to +7. However, the info on the right side of the article shows a -3 state. Which is right? ~2025-32918-34 (talk) 00:58, 12 November 2025 (UTC)

Fixed (changed it to "−3 to +7"). Double sharp (talk) 03:50, 12 November 2025 (UTC)
