Question

electronic Configuration of Cu and Cr
​

Answer 1

Answer:

Cu = 29 = 1s² 2s² 2p⁶ 3s² 4p⁶ 4s¹ 3d¹⁰ These electronic configuration are exceptional because electrons entered in 3-d orbitals without filling the 4s orbitals complete. Reason for the Exceptions ⇒ It is said that d orbitals can be stable if it is half filled or full filled.

Answer 2

[Ar] 3d¹⁰ 4s¹ =°> of cu

[Ar] 3d⁵ 4s¹==> of cr
