“…Jorgensen (4) who applied it to the break at a half-filled 3d subshell in the third ionization potentials of the transition elements. It is equally applicable, but with a different numerical constant, to the break in ionization potentials at the half-filled 2p subshell and to the bond energies under consideration here.…”

Bond energy calculations are ordinarily covered in an introductory chemistry course, but then very little use is made of them. Thus, most textbooks give a table of single bond energies and illustrate its use for a few simple carbon compounds. Then bond energies may be used in a calculation of the resonance energy in some molecule such as benzene, but they are almost never mentioned in connection with the chemistry of any elements except carbon. Very few of the tabulations even attempt to list an N-0 or S O bond energy.This situation is easily understandable since the standard treatment of bond energies gives useful results only for stable molecules with nealieible ~i bond reso-CH,, and NH together with the fact that an even number is easier to use here than an odd one.

Einen geradlinigen Zusammenhang zwischen der Elektronen‐Grundkonfiguration des neutralen Atoms eines betrachteten Elements und seiner Chemie gibt es nicht. vor allem hängt die Wahl des Oxidationszustandes von der Bilanz aus den nacheinander am freien Ion aufzuwendenden Ionisierungsarbeiten und der jeweiligen Hydratations‐oder Madelung‐Energie ab, durch die bevorzugt höhere Oxidationsstufen stabilisiert werden. Besondere Liganden wie das Oxid‐Ion vermögen unerwartet hohe Oxidationsstufen auszubilden. Am spezifischen Beispiel der Elemente Vanadium unt Thorium werden die Schwerpunktslagen von Elektronenkonfigurationen diskutiert. Eine Betrachtung der Chemie der Elemente mit der Ordnungszahl Z=101, 102, 103, 104, 105 und 112 (von denen man bisher nur einige tausend Atome erhalten hat) und der (noch unbekannten) Element mit Z=108, 109, 114, 126, 164 und 184 schließt sich an.
