Why Cerium has this charge

Cerium is an lanthanide. Its chemistry can be specialized, but +3, +4 is the most useful introductory reference range.

This is a classroom reference range, not an exhaustive list of all oxidation states.

Cerium charge examples

CeCl3

Cerium chloride

Ce3+ balances chloride ions.

Ce2O3

Cerium oxide

Cerium can form oxides where total positive and negative charge balances.

FAQ

Is Cerium 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.
