WebThe halogens generally show many of the properties typical of non-metals. They are poor conductors and have low melting and boiling points. Halogen ions are called halides and are usually negative ions with a charge of -1. Reactivity and electronegativity decrease as you go down the group whilst atomic radius and melting and boiling point increase.
