    Do we need to know these off by heart? Will we not be given a sheet of ionic charges with the periodic table we're given at the beginning of the exams? Thanks.

      Sadly Henry, we do need to know these off by heart.

      Not entirely- you should be able to tell each element's charges by their placement on the periodic table.

    If the element is in group 1 it has a charge of +
    Group 2= 2+
    Group 3 = 3+
    Group 5 = 3-
    Group 6 = 2-
    Group 7 = -
    Group 8 = neutral
