![]() E. C. Stoner |
E. C. Stoner (physics) E. C. Stoner publishes a paper pointing out that for a given value of the principal quantum number (n), the number of energy levels of a single electron in the alkali metal spectra in an external magnetic field, where all degenerate energy levels are separated, is equal to the number of electrons in the closed shell of the rare gases for the same value of n. This leads to discovery of the Pauli exclusion principle. |
