In Universe L, recently discovered by an intrepid team of chemists who also happen to have studied interdimensional travel, quantum mechanics works just as it does in our universe, except that there are three d orbitals instead of the usual number we observe here. Use these facts to write the ground-state electron configurations of the fifth and sixth elements in the first transition series in Universe L. Note: you may use X to stand for the electron configuration of the noble gas at the end of the row before the first transition series.
