In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation.

In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity. 2020-08-13 · 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.

If a photon of light is absorbed its energy (h\( u\)) 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=\(\lambda u\)).

Razvio je Bohrov model atoma , u kojem je predložio da su nivoi energije elektrona diskretni i da se elektroni vrte na stabilnim orbitama oko atomskog jezgra , ali mogu skočiti sa jednog energetskog nivoa (ili orbite Bohr's model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. Bohr found that an electron Bohr's Atomic Model The model of Niels Bohr (1885–1962) for the atom is since long just the one and only conception for atoms of the vast majority of educated Niels Bohr developed his model of the atomic structure in 1913 that succeeded in explaining the spectral features of hydrogen atom.

This model of Bohr’s idea of the atomic structure shows how it works. 2020-07-26 Niels Bohr worked with Ernest Rutherford and helped Rutherford revise his atomic model because their were some problems with it. While revising, Bohr discovered that electrons travel in separate orbits around the nucleus. 2020-08-16 Niels Bohr and the Atomic Model Timeline created by abrindus.
