Pick any of the hundred and eighteen elements and see every orbital it has, drawn from the hydrogen-like solution at the effective nuclear charge Slater’s rules give its subshell. The radial nodes are real: a 3s has two, and both are on screen.
Each element’s page carries its ground-state configuration, the subshells it fills, their energies in eV and the mean radius of each — and, for the twenty elements that disagree with Madelung order, both the predicted configuration and the one the atom takes.
Atomic orbitals, hybridisation and molecular orbitals, computed and drawn in your browser. The tool needs JavaScript and WebGL2; these are the pages it offers:
