English edit

Etymology edit

From Ancient Greek ἅλς (háls, salt" or "sea) + γεν- (gen-), "to produce" (coined by Berzelius in 1842).[1]

Pronunciation edit

  • enPR: hălʹə-jən, hāʹlə-jən
  • IPA(key): /ˈhæl.ə.d͡ʒən/, /ˈheɪ.lə.d͡ʒən/
  • (file)

Noun edit

halogen (plural halogens)

  1. (chemistry) Any element of group 17, i.e. fluorine, chlorine, bromine, iodine, astatine and tennessine.
  2. A light fixture in which the filament is surrounded by an atmosphere of a halogen gas.

Usage notes edit

When the term was coined, all known group 17 elements formed salts on reaction with a metal. This may not be true for the recently discovered superheavy element tennessine, though experiments cannot yet be carried out because of its short lifetime. Chemists usually include tennessine as a halogen to extend the term to all of group 17, though those specialising in the chemistry of superheavy elements may exclude it.
