Nomenclature Worksheet 3: Ionic Compounds Containing Polyatomic Ions Please complete the following table: Formula of Ionic Compound C (Is CIO An anion is an atom that has gained a valence electron and is negatively charged. Or, you can use what you know about energy levels - that the atomic number is also the number of electrons - and place the electrons in their corresponding energy shells to determine how many are left in the outermost shell.
