|Abstract:||The article presents the exotic electronic structure of f-elements and as a result their characteristic chemical behaviour. One of the determining factors of their strange behaviour are the relativistic effects, which consist of scalar and spin-orbit interactions. The differences of the oxidation numbers between lanthanides and actinides were investigated, which are mostly caused by the more pronounced relativistic effects of actinides. The lanthanide contraction was interpreted as well as the similar actinide and d-element contractions which are less important in practise. Although in the last decades significant development occurred in computational chemistry, the calculation of the f-elements is still a challenge, since the inclusion of both the relativistic effects and the electron correlation is crucial.|
