FAQ

Is Bromine 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.
