Document Summary
Proposed an explanation for the tiny deviations that had been observed (spectral lines) Suggested that an electron behaves in some respects like a spinning sphere. An electron has two spin states represented by arrows up and down or the greek letters alpha and beta. The two spin states are distinguished by a fourth quantum number, the spin magnetic quantum number (ms) This number has two values: + (up electron) and - (down electron) To summarize, an electron has the property of spin; the spin is described by the quantum number ms = 1/2. In the ground state, the electron is in the lowest energy, the state with n = 1. The electron in the ground state of a hydrogen atom is described by the following values of the four quantum numbers: The electron can have either spin state.
