You have reached the end of Physics lesson 20.1.4 Bohr's Atomic Model. atomic nucleus contains other particles inside. Is it an object without any internal structure that only manifests some special features or maybe there are other elements inside it? Further investigations and experiments confirmed the second hypothesis, i.e. Now, the next question that arose regarded the structure of atomic nucleus. Although now this model is outdated, it is still used for convenience to describe the atom, especially in explaining the energetic levels of hydrogen atom. In a certain sense, the Bohr's atomic model represents the beginning of modern quantum mechanics. " An atom (electron) can emit or absorb radiation only during its transition from one stationary energetic level (orbit) into another." An electron can make a transition from a stationary state of higher energy E 2 to a state of lower energy E 1 and in doing so, it emits a single photon of frequency f, the value of which, is given byĪ generalized version of the second postulate would be: Such orbits are called stationary orbits. The postulate of stationary states: An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy.With his atomic model, Bohr proposed two courageous postulates: This prevents them from losing energy during such revolutions. The issue of atom's stability was resolved by Bohr, who in 1913 proposed a new model, in which electrons move in determined circular orbits around the nucleus, similarly to the revolution of planets around the Sun.
