oxidation numbers of transitional metals

Postby Abigail Urbina 1K » Mon Feb 19, 2018 4:01 pm

In determining the oxidation numbers of transitional metals, does it all just depend on the charges of the other atoms it forms a molecule with? Like for example, in the compound MnO4-, does the 7+ charge depend solely on the oxygen charges? Do we rely on the non-transitional metals in an ion as well as its charge to determine oxidation states?

For transitional metals, as you stated, it depends on the oxidation numbers of the other atoms present in the molecule. For MnO4-, you know the O's will have 2- each for a total of 8-. Because the overall compound has a charge of -, you know the Mn has to be 7+ to make this true.
