    Wasnt it just drawing the Iodine with a full shell, one extra elctron so it had a negative charge?

    Anyway I found that paper really hard! The first page just bamboozled me, I thought it got better as it went on though. The last section was pretty easy, about the article.
    Was does it mean if it's (I) next to the molecule, I said the chlorine had a 1+ charge.
    it didn't ask to draw the shell, did it? :s. there was only one line and it asked to give the outermost subshell of an iodide ion.

    and the (I) is the oxidation state of the chlorine in that compound. it's a +1, not 1+.

    Yeah, so don't you just draw the outermost electrons :confused:

    Don't think they would have asked you to work out all the sub shells seeing at the proton number was 53?

    I said chlorine could be used as a solvent lol. It was one of the simplest question, I just for some reason had no idea what the anwer was.

    tbh, i don't know what to believe. i interpreted the question as giving the last subshell and everyone's saying something else :/. my friends and i agree on the last subshell thing.
    then i'm reading all sorts here;

    would chlorine being a CFC, be a viable use of chlorine?

    I'd like to thank Hudz too for his document, proved very useful. Maybe i should have read it in more detail, but hey can you produce more materials like that for A2 please :P?

    On the whole the paper was ok.

    I don't think so, since CFCs are no longer used!
    I put bleach, which according to past papers I've done IS a different point to water purifying. So I hope I got that mark!

    Made a few silly errors but I think the paper went quite well as a whole... I guess I'll see in August

    Their still used in developing countries! I think similar questions in past papers accepted CFC's as an answer.

    Oh, really? I haven't noticed that before but if they do then yeah, CFCs might get you the mark.
    Seems a bit odd though considering the atmosphere questions often mention how CFCs aren't used any more...

    Off topic but I heard that Salters is seen as a better/more rigorous qualification by universities than, say, AQA Chemistry or the OCR A specifications.

    Is this true?
