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 four d orbitals instead of the usual number we observe here. Use these facts to write the ground-state electron configurations of the third and fourth elements in the first transition series in Universe L .

See explanation

Explanation:

The third element in the first transition series is Vanadium

The fourth element in the first transition series is chromium

Given that we have four d orbitals in universe L instead of five as we have on earth;

The electronic configuration of Vanadium in universe L is;

Ar 3d3 4s2

The electronic configuration of chromium in universe L is;

[Ar] 3d4 4s2
