Bk2O3

Berkelium oxide

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

FAQ

Is Berkelium 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.
