Question

10. The electronic configuration of valence shell of Cu is 3d 4s' and not 3d 4s. How is this
configuration explained?​

Answer 1

Explanation:

Configuration with completely filled and half-filled orbitals have extra stability. In 3d104s1, d-orbitals are completely filled and s-orbital is half- filled. Hence, it is a more stable configuration

Answer 2

Answer:

Configuration with completely filled and half-filled orbitals have extra stability. In 3d^104s^1, d-orbitals are completely filled and s-orbital is half- filled. Hence, it is a more stable configuration.
