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 … WebJun 30, 2024 · Sommerfeld extended Bohr's atomic model to include orbits of varying angular momentum, where the orbits are elliptical and become gradually less eccentric as the angular momentum increases [8, 9]. He quantized the angular and radial motion separately with quantum numbers for each but, as Bucher [ 10 ] discusses at length, he …

WebDec 23, 2024 · Niels Henrik Bohr (1885-1962) was a Danish physicist who developed the atomic model and won the 1922 Nobel prize in physics. "Bohr's model of 1913 for the hydrogen atom had circular electron orbits about the proton — like Earth orbits around the sun," says Herschbach. "Bohr had made use of a simple and regular pattern for the … 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.
