    I hope this helps clarify anything
    I wasn't sure of the answer either
    I wrote Argon as well, but out of stupidity because I thought the last question was about sulfur the next one couldn't possibly be about sulfur too. There is a larger jump from 6 to 7 in sulfur in comparison to argon, that's why I don't think it could be Argon. I just hope writing argon doesn't make us lose all the marks.

    I somehow doubt it.. That should have been addressed before you went in, not just when you get a question wrong
    I know, I only realised after when I looked at the packet details. I thought my vision was a bit blurry because I was so nervous and slightly nauseous . But that was the only one I had on me

    I wrote argon too, we'll definitely lose all the marks. If you write the wrong thing the mark scheme says CE = 0 meaning you can't get any marks if you write the wron answer even if your explanation is justifiable
