👤 whose
Whose work explained that electrons fill orbitals in patterns across the periodic table?
Quick Answer
Erwin Schrödinger’s and Werner Heisenberg’s quantum mechanics did. It replaced simple shell models with orbitals and probability clouds.
The Full Story
Quantum mechanics, developed in the 1920s by scientists including Erwin Schrödinger and Werner Heisenberg, explained electrons as occupying orbitals rather than fixed paths. This gave a deeper reason for the structure of the periodic table, especially the filling of s, p, d, and f blocks. Electron configuration determines an element’s chemistry and its place in the table. The periodic table is therefore a map of quantum behavior as much as chemical properties.
