The stability of half-filled and completely filled orbitals arises from symmetrical distribution of electrons and exchange energy. In atomic structure, orbitals within the same subshell possess equal energy, and when they are half-filled or fully filled, electron repulsion is minimized while exchange interactions are maximized. For example, in the 3d subshell
