    In the chemistry spec it says deduce the electron configurations of:

    atoms, given the atomic number, up to z = 36.

    What is z = 36?

    'Z' is the atomic number of an atom, or the number of protons in the nucleus of an atom. When it's neutral the number of protons is equal to the number of electrons.

    So looking at a periodic table you read Hydrogen as (z=1), Helium as (z=2) and so on up to Krypton (z=36).

    I s'pose that means you'll just have to work out the configuration of anything between 1 and 36. That should be okay, it's mostly in order bar two(?) exceptions but I guess you'll learn about that.
How are you feeling about your exams?
