On my user talk page, i wrote:

“See “Category:en:Lanthanide series chemical elements” and “Category:en:Actinide series chemical elements”. These should be titled “Category:en:Lanthanides” and “Category:en:Actinides”. Please avoid such blatant clutter. And why is “Category:en:Lanthanide series chemical elements” placed in Category:en:Radioactivity? Only one lanthanide, promethium, is radioactive. Also, there is debate over whether lanthanum, lutetium, or both count as lanthanides, so i recommend that both article be placed in “Category:en:Lanthanides”. Likewise, there is debate over whether actinium, lawrencium, or both count as actinides, so again, i recommend that both article be placed in “Category:en:Actinides”.”--Solomonfromfinland (talk) 04:41, 27 April 2022 (UTC)
