Question

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 .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.

Answer 1

Answer:

See explanation

Explanation:

The third and fourth elements in the first transition series are vanadium and chromium. They contain 23 and 24 electrons respectively.

In universe L, the electron configuration of vanadium is;

[X]  3d3 4s2

In universe L, the electron configuration of chromium is;

[X] 3d4 4s2

The electron configuration of chromium has to change since there are four instead of five d orbitals in universe L.
