calcium carbon compound
Calcium ions can balance common negative Carbon ions.
Ionic charge is the charge on an actual ion. Oxidation state is a bookkeeping number used inside compounds. They can match, but they are not always the same thing.
Combine positive and negative ions so the total charge is zero. You can also use the ionic compound calculator.
Use the periodic table with charges or the ionic charges chart.
