### Oxidation number

Can anyone explain the steps to finding the oxidation number in coordination compound? Are we going to have to know how to do this for our final?

I just looked at this link and it seems to cover everything! https://socratic.org/questions/how-do-y ... a-compound

I too am curious about if we'll have to have this memorized for the final...

### Re: Oxidation number

The sum of oxidation numbers for a neutral compound is 0 and the sum of oxidation numbers for a polyatomic compound is the charge of the ion. By knowing specific charges for atoms (e.g. Hydrogen has a charge of +1), you can do basic algebra to solve for the charges of the other atoms.

Oxidation number is the same as formal charge except bonding pairs are not split equally. They are both assigned to the more electronegative atom.
Oxidation number = V - LPE - (BE shared with less electronegative atoms)

Will we be expected to remember the charges of common polyatomic compounds for the final?
