The energy levels of atomic orbitals in multielectron systems demonstrate that the 3d orbital has a higher energy than the 4s orbital despite the greater distance from the nucleus and increased shielding effect associated with the 4s orbital. This phenomenon is attributed to angular momentum and spin characteristics of the orbitals. The discussion references specific resources that elaborate on the relationship between these orbitals and their energy levels.
