WebbBohrs atommodell är den av Niels Bohr 1913 uppställda teorin för atomen enligt vilken elektronerna rör sig i cirkulära banor runt atomkärnan, där centripetalkraften ges av coulombkraften och rörelsemängdsmomentet är kvantiserat till ett heltal gånger Plancks konstant, nh/2π. Detta leder till att elektronen endast kan inta vissa specifika energinivåer.

WebbThe Bohr model provides a theoretical framework for understanding line spectra. If a photon of light is absorbed, its energy (h\(\nu\)) is transferred to an electron which jumps from a low energy orbit to a high energy orbit, and the absorption spectral lines are correlated to wavelengths associated with the frequency of that light (c=\(\lambda \nu\)).

WebbWith 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. WebbThe Niels Bohr Atomic Model theory is a model that was introduced by Niels Bohr in 1913 to describe the atom. It was a postulation of Bohr that the electrons rotated in a circular orbit around the nucleus of the atom. Niels Bohr’s atomic model was created based on previous research by Rutherford, Rutherford’s gold foil experiment, and ...

WebbBohr's model had one significant drawback - they were only a 2-D diagram of the truth. In reality the actual model of the atom is the Sommerfield atom, where we see electrons travelling in an elliptical path around the nucleus, but in the xyz plane. In plain words, Bohr's model was a 2-D shape while Sommerfield's was a 3-D shape of an atom.
