WP: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).

[edit] Goals

watch · refresh · history

Short term
  1. Wikify the last Preacautions section of radon so it can be submitted for GA/FA.
  2. Bring the vital article Carbon to GA then FA standard.
  3. Fix the issues that resulted in the WP:VITAL articles Copper and Aluminium delisting as GA
Mid term
  1. Bring all B-class vital articles (Gold, Iron, Nitrogen, Silicon, Silver) to A-class or above
  2. Bring all the remaining d-block elements (yttrium, hafnium, tantalum, rhenium, osmium, and iridium) and astatine from start to a B-class level.
  3. Bring Discoveries of the chemical elements and Periodic table to GA standard (or above).
  4. Bring the rest of the Noble gases (Neon, Argon, Krypton and Radon) to FA-class and then make noble gas a featured topic
Longer term
  1. Bring the rest of the articles marked as WP:VITAL on the Articles subpage (Aluminum, Sulfur, Copper, Gold, Iron, Nitrogen, Silicon, Silver) to FA standard (4/13 = 31% as of 6 Feb 2008)
  2. Bring all articles marked as Top Importance on the article subpage to GA standard or above.
  3. Bring all articles marked as High Importance on the article subpage to A-class (or above).
Ultimate goal Featured article
  1. Bring all element and supporting articles to FA standard (turn the Periodic Table by Quality blue)

This common arrangement of the periodic table separates the lanthanides and actinides from other elements. The Wide Periodic Table incorporates the f-block. The Extended Periodic Table adds the 8th and 9th periods, incorporating the f-block and adding the theoretical g-block.
