Manganese(II) oxide facts for kids
Manganese(II) oxide is a special kind of chemical compound. It's made from two elements: manganese and oxygen. Its chemical formula is MnO. This means one atom of manganese is joined with one atom of oxygen.
In this compound, manganese has a specific "charge" or "power level" called an oxidation state of +2. Think of it like a team where manganese is playing with a certain energy level.

How is Manganese(II) Oxide Made?
Manganese(II) oxide can be made in a few ways. One common method involves changing another manganese compound.
Changing Manganese(IV) Oxide
You can make MnO by taking manganese(IV) oxide and performing a chemical process called reduction. Reduction means taking oxygen away or adding electrons.
To do this, you heat manganese(IV) oxide with certain gases. These gases act like helpers to remove oxygen. The helpers can be:
- Hydrogen gas
- Carbon monoxide gas
- Methane gas
Heating Manganese Carbonate
Another way to create manganese(II) oxide is by simply heating a substance called manganese carbonate. When you heat manganese carbonate, it breaks down and forms manganese(II) oxide.
What is Manganese(II) Oxide Like?
Manganese(II) oxide is usually a green or gray-green solid. It doesn't dissolve easily in water. It's often used in different industries, for example, in making ceramics or as a part of fertilizers.
