Transition Metal Oxidation Number
How is CuO formed, when Cu only has 1 electron (4s1) and oxygen needs to take 2 electrons in (2s2 2p4)?
To me it seems that Cu would have an oxidation number of +1, but I don't think that is the case. Is an electron donated from the 3d orbital? If so,
would the 3d10 become 3d9?

It takes the electron from 4s and 3d. It CAN have an oxidation number of +1. The thing is that the 4s and 3d are basically degenerates (same energy)
so it can remove the electrons from 4s and 3d.

Ohhhh. I didn't know that the 4s and 3d had the same energy...Well, I figured it must be something like that. Thanks for the help.
