Sommerfeld extension of bohr theory
WebMay 29, 2024 · Just as Sommerfeld’s extension of Bohr’s model had opened a route toward quantum mechanics, his semiclassical electron theory (1927) paved the way for the quantum theory of solids. However, it would be misleading to sum up his contributions only as a hinge between classical and modern physics—a transition that deserves critical … WebApr 6, 2024 · Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models. The Bohr model and all …
