Here, some of the properties of two super heavy elements viz. Copernicium (Cn) and Flerovium (Fl) are discussed. The half life time, transition probability, Gamow’s factor, disintegration constant are calculated for these super heavy elements and compared with other values. ©2016 Science Front Publishers Keywords : Transition probability, semi empirical mass formula, disintegration constant, tunneling effect 1. Introduction From the early days of the synthesis of heavier transuranic elements, it was predicted that since such heavy elements did not occur in nature, they would have shorter and shorter half lives. A doubly magic isotope having magic numbers of proton and neutrons would be stabilized against radioactive decay. The doubly magic isotope after lead-208 is flerovium-298 with 114 protons and 184 neutrons. It forms the centre of a so called ‘island of stability’. This island of stability centering around elements 112-118 comes just after a ‘sea of instability’ from elements 101-111. The Flerovium isotopes in it were speculated in 1966 and it’s half lives were estimated to be more than a hundred million years.
