Half a century ago the unique chemistry of the light homologs was corre-lated to the then available atomic orbital (AO) radii. ![]() T The Periodic Table, and the unique chemical behavior of the first element of a group, were discovered simultaneously one and a half centuries ago. Some physicochemical properties, especially for the 5f-series, when we have some available data on theĤf-series as well as the mathematical function of the causal correlation between these two nf-series. For this issue, we can contribute to the complement of periodic table of elements by Values, especially for the actinides for which the half-life is very short or the experimental conditions are very In this context, we have suggested some expressions relating these properties and interesting toĮstimate or predict, by interpolation or extrapolation methods, some eventually not available experimental Similarities are manifested in a strong causal correlation between certain properties by linear or S-shapedīehaviors. ![]() ![]() Ions explained by a similar electronic configuration, ionic radius and same hydration number. This study contributes to demonstrate similarities in transport and structure properties between 4f and 5f trivalent Ionic self-diffusion coefficients D of some trivalent lanthanide and actinide ions have been determinedīy the open-end capillary method (O.E.C.M.) in supporting lanthanide electrolyte 1 : 3 aqueous solutionsĪt 25☌ and optimal pH 2.50 in order to avoid hydrolysis, ion pairing and complexing of trivalent 4f ions.
