*For a general electronic configuration of " l k ", namely k equivalent electrons occupying one subshell, the general treatment and computer code could also be found in this paper.

The term " fine electronic structure " means the existence of a structure close lying many-electron energy states, derived from the abolition of degenerate electronic configurations of a paramagnetic atom or ion.
33.
For example, the extant members of the group routinely accept an electron to achieve the more stable electronic configuration of a noble gas, one having eight electrons ( octet ) in its valence shell.
34.
An example provided in Slater's original paper is for the iron atom which has nuclear charge 26 and electronic configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 6 4s 2.
35.
The oxidation state + 3 originates from the [ Rn ] 6d 1 7s 2 electronic configuration of actinium, with three valence electrons that are easily donated to give the stable closed-shell structure of the noble gas radon.
36.
The concept of magic numbers ( in the field of chemistry ) was first recognized by inspecting the intensity of thiolate-protected gold clusters; here the outstanding stability of specific cluster sizes is connected with their respective electronic configuration.
37.
The " d " 9 electronic configuration of this ion gives three electrons in the two degenerate Lewis basic ligand and any electrons in orbitals with a " z " component, thus lowering the energy of the complex.
38.
After a series of early sculptural and kinetic works, in the early 1990s Penny created Petit Mal, which he presented internationally from 1995 to 1997 and again in 2006 after a careful restoration that maintained the original electronic configuration of the piece.
39.
The maximum coordination number for a certain metal is thus related to the electronic configuration of the metal ion ( to be more specific, the number of empty orbitals ) and to the ratio of the size of the ligands and the metal ion.
40.
Based on that idea, modern pseudo-potentials are obtained inverting the free atom Schr�dinger equation for a given reference electronic configuration and forcing the pseudo wave-functions to coincide with the true valence wave functions beyond a certain distance rl _ ..
