Semi-protected edit request on 20 May 2018

The periodic table has a lot of mistakes. For example, Ta and Cm are not alkali metals and Hf and Am are not noble gases are to just name a few. Can you please fix all of the mistakes? 75.67.58.188 ( talk) 12:33, 20 May 2018 (UTC) reply

 Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. Eggishorn (talk) (contrib) 18:12, 20 May 2018 (UTC) reply

Suggestion to mainly switch to a compact 18-column format and make all en:Wiki templates of this sort consistent

Just in case you watch this page but not the one for the periodic table itself, please be aware that there is a current discussion which, if successful in reaching a consensus, would largely replace this template with a new 18-column compact template (to make it easier to click cells and give extra information). You can see the issue particularly at any infobox for an element: compare Neon, for example, where this template is used for the infobox and at the bottom of the article. Please make any comments there, not here. Michael D. Turnbull ( talk) 17:26, 22 July 2020 (UTC) reply
