    Hello....
    I am clearly a novice AS OCR chemistry (A) student and I need help please....
    I need some general guidance to state symbols e.g. Water is (l) nitrates are generally (aqueous), are metals solid apart from Mercury?

    Basically, anything that is a precipitate in a reaction is (s), any pure liquid is (l) (usually only water), and anything dissolved in anything else, so pretty much all acids and alkalis, are (aq). Hope I helped.

    Surely you did this at GCSE.

    aq = aqueous
    g = gas
    l = liquid
    s = solid

    Yes all metals are solid apart from Hg. You will not find Hg reactions in your course. If you do I'll be one of the first to know!

    Do you mean bonded? Well they form ions that depending on what you're reacting them as will probably be dissolved therefore (aq). If they become precipitated then (s).

    On their own Group 7 are (g) and Group 1 (s).

    F2 and Cl2 are gases, Br2 is liquid and I2 is solid (at RTP)

    Indeed they are, I should probably read my textbook again.
