FAQ
Is Tin charge the same as oxidation state?
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.
How do I use this in formulas?
Combine positive and negative ions so the total charge is zero. You can also use the ionic compound calculator.
Where can I see the full chart?
Use the periodic table with charges or the ionic charges chart.
