The Halogens
Chemical properties
-
They become stable by
- gaining an electron from a metal, forming a halide ion in an ionic compound
- sharing an electron with a non-metal in a covalently bonded compound

Reaction of halide ions
-
Halogens = oxidising agents, they are REDUCED
Halides = reducing agents, they are OXIDISED
A more reactive/oxidising halogen will displace a less reactive halogen from a compound - DISPLACEMENT
