      It’s been over 20 years, but why is 5s1 4d10 a correct representation and not 5s2 4d9?

      Edit: is it because d10 is more stable than d9? But then s1 is less stable than s2.

        Half and full filled configurations are more stable. s1 is still half filled and d10 is full filled. The net effect it better stability even if s became a little less stable
