When we write electron configurations, do we write 3d, 4s or 4s, 3d?

I think we are supposed to write them as 3D, 4S because it is then easier to see where the electron is being removed from in ions.

Dr. Lavelle explained that the configurations should be written in order of energy level, so 3d would come before 4s.

You should put 3d before 4s since when 3d is filled it has lower energy than 4s.
