Re: Oxidation number
The sum of oxidation numbers of each component is the complex's overall charge.
Anions have oxidation numbers equal to their charges. This includes anion ligands.
Neutral ligands have oxidation number 0.
Cations with fixed charges (like K[sup]+/sup]) have oxidation numbers equal to their charges.
From there, the only unknown oxidation number is that of the transition metal, and you can figure out what oxidation number the transition metal should have to have the total oxidation number equal the formal charge.

Re: Oxidation number
To find the oxidation number of a TM:
1) take the sum of all the oxidation numbers of each component bound to the central TM atom
2) find the overall charge of the molecule (usually given)
3) subtract the overall charge by the sum of all oxidation numbers stated in part 1

Re: Oxidation number
You just need to take the sum of all the oxidation numbers and then subtract the overall charge from that to get the charge/oxidation number of the transition metal.
