Hi, I need help with something. What are the correct formulas and names of manganese and oxygen compounds.

Well, there are only a few thousand Mn compounds and a few hundred thousand oxygen compounds. I suggest you look in something like "The Merck Index" or "Handbook of Physics and Chemistry" for this.

No as in compounds only using Mn and O like MnO Mn20 etc

Here is a listing.

Of course, I can help you with that!

To determine the correct formulas and names of manganese and oxygen compounds, we need to consider the oxidation states of manganese and oxygen, as well as their combining ratios.

1. Manganese Compounds:
Manganese can exhibit several oxidation states, with the most common ones being +2, +3, +4, +6, and +7.

- Manganese(II) compounds have Mn2+ as the manganese ion. An example of a manganese(II) compound is Manganese(II) chloride, which has the formula MnCl2.
- Manganese(III) compounds have Mn3+ as the manganese ion. An example of a manganese(III) compound is Manganese(III) oxide, which has the formula Mn2O3.
- Manganese(IV) compounds have Mn4+ as the manganese ion. An example of a manganese(IV) compound is Manganese(IV) oxide, which has the formula MnO2.
- Manganese(VI) compounds have Mn6+ as the manganese ion. An example of a manganese(VI) compound is Manganese(VI) oxide, which has the formula MnO3 (although this compound is relatively unstable).
- Manganese(VII) compounds have Mn7+ as the manganese ion. An example of a manganese(VII) compound is Manganese(VII) oxide, which has the formula Mn2O7.

2. Oxygen Compounds:
Oxygen commonly has an oxidation state of -2 in most compounds. Combining oxygen with metals will result in metal oxides.

- Oxides containing a single oxygen atom will have the prefix "mono-". For example, MnO is Manganese(II) oxide.
- If a metal forms more than one oxide, the one with a higher oxidation state will have the suffix "-ic" and the one with a lower oxidation state will have the suffix "-ous." For example, MnO2 is Manganese(IV) oxide, and Mn2O3 is Manganese(III) oxide.

It's important to note that manganese and oxygen can form different compounds depending on the specific conditions and other elements involved.

I hope this helps! Let me know if you have any more questions.
