Superheavy elements: existence, classification and experiment
  This paper proposes spatial periodic table developed based on classic electron shell structure model. The periodic table determines location and chemical properties of superheavy elements. 14 new long-living superheavy elements found by Proton-21 laboratory and one long-living superheavy element found by A.Marinov were identified.
