Hund's Rules for Filling Degenerate Orbitals (Friedrich Hund)
Electrons are added to a subshell with the same value of the spin quantum number until each orbital in the subshell has at least one electron.
Hund's rules can be understood by assuming that electrons try to stay as far apart as possible to minimize the force of repulsion between these particles.

Friedrich Hund (1896-1997) was the first to make use of quantum mechanical barrier penetration in discussing the theory of molecular spectra in a series of papers in 1927.
As illustrated in figure 1, Hund was primarily concerned with characterizing the electronic energy eigenfunctions in terms of the quantum numbers for the limiting cases of united and widely separated atoms, as the distance between the atoms is changed adiabatically from zero to infinity.
Hund assumed the separability of the electronic motion from the vibration and rotation of the atoms, an approximation later made quantitative by Born and Robert Oppenheimer.

 Hund's Rule History - Hund's Rule Information
Developed by the German scientist, Friedrich Hund (1896-1997), Hund's rule allows scientists to predict the order in which electrons fill an atom's suborbital shells.
Hund's rule is based on the Aufbau principle that electrons are added to the lowest available energy level (shell) of an atom.
Although Hund's rule accurately predicts the electron configuration of most elements, exceptions exist, especially when atoms and ions have the opportunity to gain additional stability by having filled s orbitals or half- filled or filled d or f orbitals.

Sepsis, steroid treatment and neuromuscular blocking agents may act as triggers in the pathogenesis of CIM (Hund, 2001, J. Neurol.248) but the exact pathomechanism of the resulting muscle weakness is far from known.
It is even not clear whether CIM reflects a predominantly local inflammatory process (De Letter et al., 2000, J. Neuroimm.106) or might be induced by a humorally spread ‘myotoxic factor’ similar to the proposed pathomechanism of CIP (Druschky et al., 2001, Intensive Care Med.27).
Methods: The sera of 5 ventilated ICU patients with clinical and neurophysiological diagnosis of CIM and 5 healthy control persons were pooled and centrifuged with molecular weight cut-off (MWCO) filters of 10, 30 and 100 kDa.
