Learning outcomes
Candidates should be able to:

1. write formulas of ionic compounds from ionic charges and oxidation numbers (shown by a Roman numeral), including:
   (a) the prediction of ionic charge from the position of an element in the Periodic Table
   (b) recall of the names and formulas for the following ions: NO3 – , CO3 2–, SO4
