WebJan 27, 2024 · The simplest example of the Bohr Model is for the hydrogen atom (Z = 1) or for a hydrogen-like ion (Z > 1), in which a negatively charged electron orbits a small positively charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted. WebThe Bohr-Sommerfeld theory provided a reasonably satisfactory explanation of the spectra of atoms having only one valence electron. With two or more electrons discrepancies occur and certain arbitrary selection rules for atomic transitions were required. In an attempt to solve this problem, several persons, including de Broglie, Schrodinger ... jamestown activity worksheet

Bohr-Sommerfeld-Heisenberg Theory in Geometric Quantization

Webtonian systems lead to Bohr-Sommerfeld theory, also called old quantum the-ory. Bohr [1] explained Planck’s hypothesis by the spectrum of the harmonic oscillator, which he obtained using his quantum conditions. Sommerfeld [19] extended Bohr’s quantization rules to a system with Hamiltonian H = p p2 +m2 + k r. (1) WebSep 29, 2024 · What did Sommerfeld discover? From 1911 his main area of interest became quantum theory. Sommerfeld’s work led him to replace the circular orbits of the Niels Bohr atom with elliptical orbits; he also introduced the magnetic quantum number in 1916 and, four years later, the inner quantum number.
