Niels bohr proposed the bohr model of the atom in 1915 because the bohr model is a modification of the earlier rutherford model, some people call bohr's model the rutherford-bohr model the modern model of the atom is based on quantum mechanics. Bohr theory n an early model of atomic structure in which electrons travel around the nucleus in a number of discrete stable orbits determined by quantum conditions.
The bohr model has an atom consisting of a small, positively-charged nucleus orbited by negatively-charged electrons here's a closer look at the bohr model, which is sometimes called the rutherford-bohr model niels bohr proposed the bohr model of the atom in 1915 because the bohr model is a.
Bohr extended lorentz's model, but was still unable to account for phenomena like the hall effect, and concluded that electron theory could not fully explain the magnetic properties of metals the thesis was accepted in april 1911,  and bohr conducted his formal defence on 13 may. Bohr atomic model : in 1913 bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus the motion of the electrons in the rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits.
Some examples of these are: the discovery of the radioactivity of thorium, and the new elements polonium and radium (1898) the identification of alpha and beta radiation (1899) the rutherford/soddy disintegration theory (1902) the discovery of isotopes (1909) the rutherford nuclear theory of the atom (1911) the bohr theory of the atom (1913) the disintegration of nitrogen atoms (1919) the discovery of artificial radioactivity (1933) and the discovery of nuclear fission (1938. The bohr model shows that the electrons in atoms are in orbits of differing energy around the nucleus (think of planets orbiting around the sun) bohr used the term energy levels (or shells) to describe these orbits of differing energy.
Work the discoveries of the electron and radioactivity at the end of the 19th century led to different models for the structure of the atom in 1913, niels bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Niels bohr, in full niels henrik david bohr, (born october 7, 1885, copenhagen, denmark—died november 18, 1962, copenhagen), danish physicist who is generally regarded as one of the foremost physicists of the 20th century he was the first to apply the quantum concept, which restricts the energy. Bohr theory definition, a theory of atomic structure in which the hydrogen atom (bohr atom) is assumed to consist of a proton as nucleus, with a single electron moving in distinct circular orbits around it, each orbit corresponding to a specific quantized energy state: the theory was extended to other atoms.
In 1913 niels bohr came to work in the laboratory of ernest rutherford rutherford, who had a few years earlier, discovered the planetary model of the atom asked bohr to work on it because there were some problems with the model: according to the physics of the time, rutherford's planetary atom should have an extremely short lifetime.

Bohr atomic 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.
