the term electronegativity .was introduced by linus pauling, who characterized on the basis ofthermodynamic data from the energies of the single bonds. in present study, the density functional theory(dft) was used to calculate electronegativity of atoms. the base of calculation is similar to pauling andmulliken methods. the results indicate that the largest value of electronegativity for fluori...

chemical hardness () and absolute electronegativity () have important applications in chemistry. inthe conceptual density functional theory (dft), these concepts has been associated with electronicenergy and the relationship with ionization energy (i) and electron affinity (a) of these concepts hasbeen given. in this study, graphical method was used in order to see the relationship with the a...

The electron affinity (EA) of the superheavy element Og is calculated by use relativistic Fock-space coupled cluster (FSCC) and configuration interaction methods. FSCC operator expansion includes single, double, triple excitations treated in a nonperturbative manner. Gaunt retardation electron-electron interactions are taken into account. Both methods yield results that agreement with each othe...
