Answer:

Since chromium had 4 electrons, which is one short of 5 electrons to get just hslf-filled. To attain a completely filled electronic configuration copper gains one electron from the d-orbital and attains the electronic configuration of (Ar) d10 4s1. Thus both Cr and Cu have exceptional electronic configuration.

Zinc (Zn), atomic # 30, is located in the “d” block in period 4; it's electron configuration would be represented as 1s2 2s2 2p6 3s2 3p6 4s2 3d10; adding up the exponents (2+2+6+2+6+2+10=30) gives us the atomic number, 30. Electron configurations can also be represented in a condensed form

Explanation:

I hope that it would be helpful.
