The 315 oxidation states in non‐metallic, non‐catenated compounds are arranged according to their Kossel number of electrons K in 81 isoelectronic series. The profound differences between the four categories (the 4f, the 5f and the d groups, and the other elements) are analyzed and compared with ionization energies I of loosely bound electrons obtained from photo‐electron spectra, and their slope (d I /d Z ). It seems difficult, but not impossible, still to prepare a few new oxidation states. The examples argon(II), copper(IV), silver(V), thulium(IV), mercury(III) and francium(V) are discussed.
