Q
what happens to the electron configuration when an ion is formed in transition metals?
A
Even though the 4s orbital fills up first, when electrons are removed, they are taken from the 4s orbital first because it’s higher in energy than the 3d orbital once they both have electrons (so no electrons will be left in 4s)
