The lanthanides and actinides are placed in the periodic table. It is shown that they can be located without changes in the structure and in the periodic system as a whole taking into account the interatomic donor-acceptor effects in f-elements. The proposed position agrees well with the physical and chemical concepts on which the system is based. It is shown that Am, Pu, and Np can be placed in groups III, IV, and V in accordance with their basic valence states and the capability to form compounds with a valence greater than the group valence. A short-form periodic table is provided in which f-elements are placed in the reverse order of periodicity.
