Question

Write electronic configurations of Cr, Cu, Zn?​

Answer 1

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.

Answer 2

Answer:

Hey...Cr=2,8,8,2

Cu=2,8,18,1

Zn=2,8,18,2
