Every Wikidata item that is a chemical element with an atomic number from 1 to 118 — every element discovered so far, and none of the hypothetical ones beyond, and that has its own English Wikipedia article, ranked by the number of Wikimedia sites with a page about it — Wikipedia's language editions, mostly, and sister projects such as Wikiquote. That counts how many communities independently thought it worth describing, and nobody can buy a place on it. The top 118 are shown.
