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 second and third 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.second transition metal: third transition metal:

In our universe, the first transition series starts from Scandium (Sc) to Zinc (Zn) in the periodic table. The electron configuration of Scandium (Sc) is [Ar] 3d1 4s2 and that of Titanium (Ti) is [Ar] 3d2 4s2.

However, in Universe L, there are three d orbitals instead of five. This means that the d orbitals can only hold a maximum of 6 electrons instead of 10.

The second and third elements in the first transition series in Universe L would be the equivalent of Scandium (Sc) and Titanium (Ti) in our universe.

The ground-state electron configuration of the second element (equivalent to Scandium) would be [X] 3d1 4s2.

For the third element (equivalent to Titanium), since the 3d orbital can only hold 3 electrons, the electron configuration would be [X] 3d2 4s2.

Please note that [X] stands for the electron configuration of the noble gas at the end of the row before the first transition series.
