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 six 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 to stand for the electron configuration of the noble gas at the end of the row before the first transition series.

fifth transition metal:
sixth transition metal:

The electron configuration of the fifth and sixth transition elements in universe L may be slight different than as it is on earth.

The electron configuration shows the distribution of electrons in atoms. In atoms electrons are distributed in orbitals. Different orbitals hold different maximum number of electrons in them.

On earth, the d orbitals are five but in universe L, the d orbitals are six. This implies that d orbitals in universe L can hold a total of twelve electrons.

The fifth transition metal is Manganese. The electron configuration of manganese in universe L is [Ar] 3d6 4s1. The  sixth transition element is iron. The electron configuration of iron in universe L is [Ar] 3d6 4s2.
