The stability of completely filled and half-filled orbitals is due to the lower energy levels of these configurations compared to partially filled orbitals.

When an orbital is completely filled with electrons, the electrons are arranged in such a way that they have the maximum possible amount of electron-electron repulsion. This results in a more stable electronic configuration because the electrons are spread out as much as possible, and the electrostatic repulsion between them is minimized. This is known as the "octet rule" for elements in the second period of the periodic table.

Similarly, when an orbital is half-filled, the electrons are arranged in a way that minimizes the electron-electron repulsion. This results in a more stable electronic configuration because the electrons are spread out as much as possible, and the electrostatic repulsion between them is minimized. This is known as the "Hund's rule" for elements in the third period and beyond.

Partially filled orbitals, on the other hand, have unpaired electrons that are more reactive and unstable, as they have the potential to form new bonds or undergo chemical reactions to achieve a more stable electronic configuration.

Therefore, completely filled and half-filled orbitals are more stable than partially filled orbitals due to their lower energy levels and the minimized electron-electron repulsion.
