Description	A few recent years have seen remarkable progress in synthesising new, 'superheavy' elements (SHE). Researchers at Dubna reached the slopes of the expected 'island of stability' around Z = 114 and N = 184. In weeks to months bombardments of isotopes of U, Pu and Cm by very intense beams of Ca-48, they discovered (mostly alpha-active) isotopes of previously unknown elements 116 and 114, as well as of element 112, all with relatively very long half-lives - up to minutes. Modem theory approaches two orders of magnitude accuracy in predicting spontaneous fission and alpha-decay half-lives of even-even superheavy nuclides. The findings of physical experiments give an impetus to chemical studies. Quantum (theoretical) chemistry studies aim at the problem of 'relativistic effects' in chemical properties of SHE to provide also some hints for experiments. As yet, only structure and energy levels of SHE atoms, and simple molecules containing light ligands can be calculated with a necessary accuracy while experim A few recent years have seen remarkable progress in synthesising new, 'superheavy' elements (SHE).
