Structural properties and the decay modes of the superheavy elements [Formula: see text] and 118 are studied in a microscopic framework. We evaluate the binding energy, one- and two- proton and neutron separation energy, shell correction and density profile of even and odd isotopes of [Formula: see text] [Formula: see text] which show a reasonable match with FRDM results and the available experimental data. Equilibrium shape and deformation of the superheavy region are predicted. We investigate the possible decay modes of this region specifically [Formula: see text]-decay, spontaneous fission (SF) and the [Formula: see text]-decay and evaluate the probable [Formula: see text]-decay chains. The phenomena of bubble like structure in the charge density is predicted in [Formula: see text], [Formula: see text] and [Formula: see text] with significant depletion fraction around 20–24% which increases with increasing Coulomb energy and diminishes with increasing isospin ([Formula: see text]) values exhibiting the fact that the coulomb forces are the main driving force in the central depletion in superheavy systems.
