Nihonium (Nh) — its atomic orbitalsNihonium is element 113: period 7, group 13, post-transition of the p block. Its ground-state configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 4f¹⁴ 5s² 5p⁶ 5d¹⁰ 5f¹⁴ 6s² 6p⁶ 6d¹⁰ 7s² 7p¹, so its outermost occupied shell is n = 7 and holds 3 electrons.Each orbital below is the hydrogen-like solution at the effective nuclear charge Slater's rules give its subshell, so its radial nodes and its angular nodes fall where the wavefunction changes sign rather than where a drawing puts them. Slater screening gives the effective charge; the energy is the hydrogen-like −13.606 Z_eff²/n², and ⟨r⟩ the mean radius of one orbital of the subshell.
