Abstract
Using a method of rapid continuous separation of elements of the side groups III and tV of the D. L Mendeleev Periodic System, developed by the authors of this work, the properties of the chlorides of curium, californium, hafnium, and the isotope 104260 were compared. The isotope 104260 had until now been identified only by physical methods. It was established that its chemical properties differ from those of the actinide elements and are close to those of hafnium. An independent confirmation of the atomic number of the new nucleus was obtained, and it was simultaneously demonstrated that the element 104 is a member of group IV. In the experiments, 12 atoms of the isotope 104260 were recorded.
