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

Answer 1

Answer:

See explanation

Explanation:

The seventh transition element is Cobalt and the eight transition element is nickel.

Since there are eight d orbitals, we have to write the electronic configuration of Cobalt as;

[Ar] 3d9 4s0

For Nickel, we can write;

[Ar] 3d10 4s0

Note that the eight d orbitals can accommodate 16 electrons.
