WebThe Bohr model was extended by Arnold Sommerfeld. Sommerfeld was able to predict all the Hydrogen atom quantum numbers. This theory is referred to today by the name "Old quantum theory".Please see also, Hazhar Ghaderi's Bachelor thesis.. The basic idea of this theory is that closed classical trajectories (not necessarily circular) lead to discrete … WebBohr's Model. In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii.
WebNov 4, 2014 · Video transcript. - In the Bohr model of the hydrogen atom we have one proton in the nucleus. So I draw in a positive charge here and a negatively charged electron orbiting the … WebConcept: Bohr’s Model: Niels Bohr by making 4 postulates solved the puzzle of hydrogen spectra. The electrons revolve around the nucleus in circular orbits. The radius around the orbit has some special values of radius. In these stationary orbits they do not radiate energy as expected from Maxwell’s laws. Energy of each stationary orbits ...
