WebWith A. Sommerfeld’s extension of the Bohr theory in 1915–1916, it was turned into a powerful tool of atomic research and adopted and further developed by German physicists in particular. The new and more general Bohr–Sommerfeld theory described the atom in terms of two quantum numbers, while Bohr had originally used only one quantum number.

WebBohr’s model had to be altered in order to allow for such decompo-sitions. He outlined this idea in a lecture in winter 1914/15, but did not publish it. The First World War further delayed its elaboration.

WebBohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have.

Web23 de dez. de 2024 · "Bohr's model for the hydrogen atom was improved by Arnold Sommerfeld in 1916," says Herschbach. "He found elliptical orbits which accounted for spectra lines nearby those that had come from circular orbits. The Bohr-Sommerfeld model for the hydrogen atom is basic, but quantum and relativity became major aspects."
