Az így létrejövő egyszeres negatív töltésű ionjaikat halogenidion oknak nevezzük, ezek sóit pedig halogenid eknek. A halogenidionok megtalálhatóak sok ásványban és a tengervízben is. A fluor a legnagyobb elektronegativitású elem, elektronegativitása Pauling-skálán 3,98, ezért vegyületeiben oxidációs száma mindig −1.
