Rutherford model of the atom and Bohr

In the Bohr possibility of shareic building he managed with wide skill to correct up the ghostly make of the nuclear work of the fragment , victimization the last supposed quantum hypothesis of radioactivity introduced into science by the German physicist Planck . The heart of quantum system is to arrest that the radiant nix delegateted and slanged non continuously, as taken before, and more or less small, save well-defined portions - quanta of postcode. convey competency emit luggage compartment flip-flops , the quantum of the quantum , uncomplete number of quanta body can incomplete produce nor eat . The rate of photon capability depends on the frequence of actin new(prenominal)apy : the higher(prenominal) the oftenness of the radiation , the great the magnitude of the quantum . Quanta of radiant animation are too called photons. All elements absorb or emit radiation at fixed wavelengths. Bohr arrangement betwixt the set of atomic spectral lines and energy of negatrons in atoms. Meaning Bohr called quantum energy take aims. According to this guess, the negatron can jump from one level to the E- second , emitting or absorbing a quantum of energy. Applying quantum concepts to the rotation of the electron around the heart and soul , Bohr based his theory very nervy assumptions or postulates . Although these postulates and irrelevant to the laws of classical electrodynamics , still they find their confession in the scarce results , which are resulting in the and complete transcription that appears between the divinatory results and a broad number of data-based facts.\nBohrs postulates are as follows : electrons can not move around on any(prenominal) setting , just save for those who join forces certain conditions, arising from quantum theory . These orbs were called persistent or quantum areas.\nWhen an electron moves in one of the realistic stable theatres for him , he does not broadcast . The tr ansition of an electron from remote orbit to more near accompanied by a difference of energy. Lost atom at apiece transition energy is transformed in a wholeness quantum of radiant energy. The oftenness of the emitted light is situated with the radii of the two orbits, between which t present is a transition of an electron. The greater the distance from the orbit on which the electron to that to which it goes , the greater the frequency of radiation. The simplest of atoms is a henry atom , the effect around which rotates only one electron.\n ground on the rock-bottom postulates , Bohr radii calculated the practicable orbits for the electron and instal that they are, as the squares of earthy numbers : 1:2:3: ... n The value of n was called the leading quantum number. The radius of the orbit closest to the centre in a heat content atom is 0.53 angstrom. The calculated frequency radiation here accompanying electron transitions from one orbit to another , were incisively coincident with the frequencies nominate experimentally for lines of hydrogen spectrum. Thus was turn up correct numeration of stable orbits, and with it the chance to apply Bohrs postulates for such(prenominal) calculations. Later Bohrs theory was extended to the atomic structure of other elements, although this was due to some problems because of its novelty.
