WebCorrect option is A) The value of Bohr radius for hydrogen atom is 0.529×10 −8 cm. It can also be written as 0.529×10 −10 m which corresponds to 0.529 A o. Was this answer helpful? 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 …
{How Sommerfeld extended Bohr’s model of the atom (1913–1916)}
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. WebDec 26, 2015 · Slide 1 Arnold Sommerfeld extended the Bohr model to include elliptical orbits Bohr’s concept of quantization of angular ... For n = 3, the allowed states are 3s, 3p, and 3d. Another modification of the Bohr Theory arose when it was discovered that the spectral lines of a gas are split into several closely spaced lines when ... timothy elliott attorney latham ny

Sommerfeld (in 1916) expanded on Bohr’s ideas by introducing elliptical orbits into … WebMar 4, 2024 · Hint: We know that the Sommerfeld model of an atom is an extended version of Bohr’s atomic model, which was formed by Sommerfeld to explain the fine spectral line phenomenon which Bohr was not able to explain. According to him electrons move in elliptical orbits in addition to circular orbits. The elliptical shape of the orbits is due to the … WebThe Sommerfeld model provides a good description of free electrons in alkali metals such as potassium (element K), which has a Fermi energy of ε F = 2.12 eV (data from Ashcroft, N.
