Abstract Quantum stabilization of superheavy elements is quantified in terms of the shell-correction energy. We compute the shell correction at spherical shape using self-consistent nuclear models: the non-relativistic Skyrme–Hartree–Fock approach and the relativistic mean-field model, for a number of parametrizations. All the forces applied predict a broad valley of shell stabilization around Z=120 and N=172–184. We also predict two broad regions of shell stabilization in hyperheavy elements with N≈258 and N≈308. Due to the large single-particle level density, shell corrections in the superheavy elements differ markedly from those in lighter nuclei. With increasing proton and neutron numbers, the regions of nuclei stabilized by shell effects become poorly localized in particle number, and the familiar pattern of shells separated by magic gaps is basically gone.
