Wikipedia:WikiProject Elements

This WikiProject has managed to standardize the articles on the known chemical elements (see Guidelines page). Now it is aimed at the maintenance of these at an agreed upon format discussed in Wikipedia talk:WikiProject Elements and at the expansion and improvement of each article to featured article quality (check out our Goals below). See also WikiProject Isotopes. For a complete list of articles covered, including talk pages and templates, click here. To see all articles covered, but not talk pages and templates, see the periodic table by quality.

In the shorter(!) term:

• Bring all the element articles to GA-class or above (turn the "Periodic Table by Quality" completely dark green and blue.) (104/124 = 83.9% as of August 2023)

and in the longer(!) term:

• Bring all element articles to FA standard (turn the "Periodic Table by Quality" completely dark blue.) (22/124 = 17.7% as of August 2023)

In each case, the important supporting articles should be understood as included. However, we understand that some topics are either innately ill-defined or have too little known to ever develop to GA/FA.
