Oxidation number

What do you look at to determine the oxidation number of the metal in a compound?

You look at the charges of the ligands and the overall charge of the compound. If the compound happens to be bound to something else, you would use those charges to determine the charge of the compound.

Look at the charges on individual ligands. Make sure everything in the bracket adds up to the overall charge of the complex.

The oxidation number of a metal can be determined by looking at the ligands bonded to the central metal atom in a coordination sphere and the overall charge of the complex. We're supposed to memorize the charges of common ligands as given on page 724 of the text book. The charges of the ligands plus the charge of the central atom must equal the overall charge of the complex.

What I always do is write out the complex compound and then whatever the transition metal is, I assign it a variable usually "X". I set the the side equal to zero and solve as if it is an algebraic equations.
