Roman Numerals

Postby Abigail Carter 4G » Sun Nov 24, 2019 10:51 pm

I understand that the Tm cation name is the roman numeral but how do you decipher what roman numeral you write? Basically, how do you figure out what the Tm cation name is?

The roman numeral comes from the oxidation state of the transition metal.

This site gives a bit more information on how to find oxidation states!

If you know the charges of the other ligands or anions, and the overall charge of the molecule, you can figure out the oxidation state of the transition metal because it must add up to the overall charge.
