Question

The electronic configuration of valence shell of cu is 3d104s1 and not 3d94s2. How is this configuration explained?

Answer 1

Explanation:

Configuration is filled with half filled orbitals have extra stability. D orbital is fully filled S orbital is half filled

Answer 2

Answer:

$answer = > \: Configuration with completely filled and half-filled orbitals have extra stability. In 3d104s1, d-orbitals are completely filled and s-orbital is half- filled. Hence, it is a more stable configuration.}$
