    it increases down the group right? If that is so is this down to the lower elecrtonagtivity and what other factors?

    Thanks.

    Increased size of atom - so has more protons, neutrons and electrons as you go down the group. I'll let you answer why this increases it's ability to reduce.

    as you go down the group there is a greater nuclear force, but there are more shells and therefore more shielding. therefore the attraction between the outermost electrons and the nucleus is reduced.

    something is reduced when it gains electrons. so the halides, down the group, are less easily reduced(or more easily oxidised, as oxidation is the loss of electrons), but are better reducing agents.
