halogen
Englisch
[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/
Audio (Southern England): (file)
Nomen
[edit]halogen (plural halogens)
- (chemistry) Any element of group 17, i.e. fluorine, chlorine, bromine, iodine, astatine and tennessine.
- 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 and the difficulty of manufacturing it. Chemists usually include tennessine as a halogen to extend the term to all of group 17, though those specializing in the chemistry of superheavy elements may exclude it.
