    Sadly, this did little more than confusing me a lot more. Any possibility you could post the answer/send in pm?

    Nicely done, I chose sleep though last night, I reckon I could have battled on. Found Silver-Rg extremely easy and blasted through them in 5 minutes flat after I'd got copper, just a shame I had no study periods from first until 5th, so had no time to give it another go earlier! Came top 40 last month, quite disappointed this time around! Hopefully next month will be better.

    You really thought I'd give the answers away?

    Cu - What do Europe and numbers have in common?
    Ag - Take some wild guesses
    Au - Shouldn't need any help
    Rg - This was really the hardest level this month?
    Can anyone help with Au please? I keep getting loads of different (wrong) answers and I don't know why :/

    Ok, can you count to 20, and do you recognise the format that the molecule has been displayed in? I would recommend working out a formula for the molecule shown.

    The Au level question is about permutations with and without repetition. Simple maths will get you the right result.

    Haven't done molecules in this form yet, I recognise the benzene rings but we haven't done structure like this yet, so that's why I'm stumped. Could you give me the name of the molecule?

    Have you seen a skeletal formula before? If not, have a quick look on the internet, find out what they are.

    I have counted the H's for you, which gives H24

    Look where they are on the periodic table.

    I'm confused as to why rhenium is last. It would be way to obvious if it was first but still...
    Does the font size and the picture of Lady Justice count for anything?

    I can't think what it'd have to do with lady justice, but font size is the key to it. Imagine if each of those element symbols had the same mass.
