Question

write electronic configuration of Cr,Cu,Zn.​

Answer 1

Answer:

Answer:

Hence the electronic configuration of Cu+ ion is [Ar]3d10. (ii) The atomic number of zinc is 30 and its electronic configuration is [Ar]4s23d10. The Zn2+ ion is formed when when zinc loses the two electrons present in the 4s orbital. ... Thus the electronic configuration of Cr- ion is [Ar]4s23d5

Answer 2

Answer:

Cr atomic no is 24

electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s1 3d5

Cu atomic no is 29

electronic configuration is (Ar) 4s1 3d10

Zn atomic no is 3o

electronic configuration is (Ar) 4s2 3d10

Explanation:

In first and second case the electron in the 4s orbital jumps into 3d because of stability

half filled and full filled orbitals are more stable
