Ca3+

"In fact Ca3+ has an ionisation enthalpy so high that it rarely occurs naturally."

Are you sure? I never, ever heard of naturally occurring Ca3+! Sounds suspicious to me... --malbi

I suspect this is true that it never occurs naturally. I think this paragraph should be reworked; it's too much about calcium and group II and not enough about transition metals. Olin

I went and revised it. Olin

Orphaned references in Transition metal

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Transition metal's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "PTSS":

From Periodic table: Scerri, pp. 392−401
From Period 1 element: Eric Scerri. 2020, The Periodic Table, Its Story and Its Significance, 2nd edition, Oxford University Press, New York, ISBN 978-0190914363. pp. 392–401, 407–420.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 18:23, 24 December 2022 (UTC)[reply]
