Per December 2022, a WP:ELEMENTS taskforce is working to re-use isotopes data. Isotopes present in Isobox <element> are reused in Infobox <element> (read & shown, automatically and real-time).
This task is to check whether the reused data indeed has all abandoned data.
The righthand (middle of page) table is the old "Main isotopes of element" data from Infobox (Gd), which does not show any more and will be deleted. File:Red x.svgN
Todo
A. Please compare & check the two tables and sources. Update the lefthand Isobox as needed.
When the situation is unclear or to be researched, leave a comment in |checknote1=.
When OK, add the following to this Infobox page (edit), inside the {{infobox ..}} template code:
{{Infobox uranium
|check = ok
|checknote1= Not sure about xyz, someone pls take a look
B. Old Infobox parameters |isotopes comment=, |isobox ref= to remove.
2.These parameters may then be deleted from the Infobox (and so disappear from the category).
For Z>=E119, there is new parameter |theoretical isotopes comment=.
The table rows ({{isotope .. / .. decay2|mn= ..}} &tc.) now have new |ref=, one per isotope.
File:Yes check.svgDone (Cf, F, Pb). For Z>=E119, there is new parameter |theoretical isotopes comment=.
C.Align the named references.
TL;DR: Named references must be checked for exact spelling (c/p). Red messages in article References section.
References can be named, defined and reused over four pages: Article, Isotopes of <element>, {{Infobox <element>}}, {{Infobox <element> isotopes}}. In the wikicode, they appear as <ref name="Hofmann2016">..</ref>, and reused as <ref name="Hofmann2016" />.
Those ref name (reused) and ref content (when redefined) must be exactly the same (true copy/paste).
Misspellings appear as red error messages in the references section of the two live articles.
Resolving: these messages are to be removed by checking and copy/pasting the <syntaxhighlight lang="text" class="" id="" style="" inline="1">ref name=</syntaxhighlight> wikicodes.
Sometimes it is easier to remove a reference (already abandoned) from the Infobox completely, after checking it is in the Isobox allright.
