Estimation of the gas phase formation enthalpies for superheavy-elements (112, 113, 114, 117, 118, 119 and 120) and some of their +1 and -1 ions

Abstract In the present work, the gaseous phase formation enthalpies for the elements (and their +1 cations) from groups 1,2, 12, 13, 16, 17 and 18 of the periodic table taken from literature [2,3], the electron integrated heat capacity [4], as well as previously calculated IE and EA [5] are employed to estimate the gas phase formation enthalpies for the superheavy-elements 112 (Copernicium, Cn), 113 (Nionium, Nh), 114 (Flerovium, Fl), 117 (Tennessine, Ts), 118 (Oganesson, Og),  119 and 120 and for some of their +1 and -1 ions. The obtained formation enthalpies (kJmol-1) for the elements are: 112 (17.955); 113 (110.360), 114 (70.716); 117 (80.138); 118 (0); 119 (53.688) and 120 (180.400).
