Category[edit]

  • Note: as of 17 August 2013, the English wikipedia has changed categorisation and background colors of nonmetal elements. Below is the new categorisation scheme. Differences are about these old categories: "other nonmetal", "halogen", "post-transition metals"

Nonmetals are subdevided in diatomic nonmetals, polyatomic nonmetals (and noble gases, unchanged). The category other/poor metals is renamed into post-transition metals without further changes. This is the new scheme:
