Electron removal from orbitals question

Postby longjump » Wed Oct 31, 2018 5:54 pm

If you are predicting which orbital an electron would be removed from to form a +1 ion, why would Mn get an electron removed from the 4s orbital and not the 3d orbital?

It's a lot more stable for an element to have a half-full s-orbital and a completely full d-orbital than one missing from the d-orbital. I don't completely remember why, but Dr. Lavelle talked about it in class.

It is better to remove from the 4s orbital because it is the outermost shell. 3d is of higher energy, but 4s is still the outermost, or valence, shell.

When you remove an electron from an atom that has a p-orbital (and no d-orbital), you remove it first from p and then from s. However, if you remove an electron from an atom that has a d-orbital, you remove it first from the s-orbital.
