%0 Journal Article %T On the Necessity of Using Element No.155 in the Chemical Physical Calculations: Again on the Upper Limit in the Periodic Table of Elements %A Khazan A. %J Progress in Physics %D 2010 %I HEXIS (Arizona) %X It is shown how the properties of different elements of the Periodic System of Elements can be obtained using the properties of the theoretically predicted heaviest element No.155 (it draws the upper principal limit of the Table, behind which stable elements cannot exist). It is suggested how the properties of element No.155 can be used in the synthesis of superheavy elements. An analysis of nuclear reactions is also produced on the same basis. %K Periodic Table of elements %K superheahy elements %U http://ptep-online.com/index_files/2010/PP-23-11.PDF
