    Are we meant to know the properties of common and relevant elements for exams or do they provide us with a periodic table? I'm just curious because I've started some AS prep-work and there are some Empirical Formula questions, however they don't give the Ar as additional information. Thanks in advance.

    P.S. I'm talking specifically about Unit 1: Structure, Bonding and Main Group Chemistry.

    Why don't you check the syllabus at the edexcel website - It probably is far more useful than anything that we have to say...

    I would imagine, however, that they do provide you with the Ar - I don't think they want to test you on your memorising the period table and all of the Atomic or Mass numbers - they want to test you on your ability to manipulate information. Why not try to get hold of some past papers and see whether a periodic table is supplied .

    You are given the periodic table on the back of the exam paper but sometimes the mass of obscure/unknown elements are given with the question. You're expected to know the mass of things like carbon, oxygen, nitrogen etc. but you can always check on the periodic table if necessary.
