The arrangement of the lanthanides in the D.I. Mendeleev Periodic System of the Elements are presented. An electronic configuration of neutral atoms of the lanthanides and actinides is given. The authors study the properties of uranium and the transuranium elements in unusual oxidation states. The results obtained in this case give valuable information on the peculiarities of the chemistry of the actinides, and their similarity and difference from other elements of D.I. Mendeleev's periodic system. A review of the process of systematic investigations of the redox reactions of transuranium elements is presented where a previously unknown heptavalent form of neptunium and uranium was discovered. Americium was also successfully converted to the heptavalent state. Electrochemical methods are discussed to study the properties of the actinides. Methods have been developed for the production of alkaline solutions of neptunium (VII) on anodes of lead dioxide, graphite, nickel, and stainless steel; for plutonium (VII), anodes of platinum, lead dioxide, and graphite: for americium (VI), anodes of americium (III) hydroxide pulp on a platinum anode.
