What is [Ar] 3d^5 4s^1 4p^3 ?
For an atom in excited state? I've searched high and low, and I am not getting on too well with electron configuration at the moment... Is it Cr^-3? I am rather lost in all this!
It is in excited state. I am not sure what it means exactly (hence why I ask), but it does affect the electron configuration, and I figured the only way it could, would be if it was charged. Cobalt has an electron configuration of [Ar] 3d^7 4s^2, and is not in excited state.
Ahh, I think I get it a bit now :b I remembered something about excited state when we talked about ozone being affected by UV etc... Couldn't quite place it in this context. So it really is just as easy as counting when ever you have the electron configuration?
