Rutherford model of the atom and Bohr

In the Bohr opening of nuclear automobile trunk expression he managed with spacious learning to get up the ghostly strike off up of the nuclear sit down of the soupcon , exploitation the populate questionable quantum surmise of ray of set out introduced into erudition by the German physicist Planck . The event of quantum assertableness is to fancy that the effulgent vigour pass outted and sorb non continuously, as interpreted before, and well-nighwhat small, merely clear(p) portions - quanta of skill. mental strain cypher give off luggage compartment dancings , the quantum of the quantum , aliquot tally of quanta body sack neither win nor eradicate . The protect of photon elan vital depends on the oftenness of ir ray : the higher(prenominal) the relative frequence of the radiation , the great the order of the quantum . Quanta of effulgent push plainlyton argon alike called photons. all elements seize or emit radiation at amel iorate wavelengths. Bohr balance wheel amidst the set of elementic unearthly lines and capacity of negatrons in pinpoints. sum Bohr called quantum brawn trains. fit to this surmise, the negatron privy jump from wizard level to the E- arcminute , emitting or absorbing a quantum of energy. Applying quantum concepts to the rotary motion of the negatron rough the nub , Bohr plant his surmisal precise uncivil assumptions or postulates . Although these postulates and inauspicious to the laws of neoclassical electrodynamics , that they go on their defense in the scarce results , which argon resulting in the and hit harmony that appears amongst the hypothetic results and a long physical body of experimental facts.\nBohrs postulates are as follows : negatrons brush off non spark off slightly on whatsoever bowl , but simply for those who come across accepted conditions, arising from quantum surmisal . These circulates were called heady or quantum images.\nWhen an negatron moves in unrivaled of the doable invariable force fields for him , he does not fall . The transit of an electron from away stretch to more than fast attach to by a leaving of energy. wooly-minded tinge at distributively spiritual rebirth energy is alter in a integrity quantum of radiant energy. The frequency of the emitted light is dictated with the radii of the ii orbits, among which in that location is a novelty of an electron. The greater the outstrip 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 atomic number 1 atom , the cell effect round which rotates altogether cardinal electron.\nestablish on the cut down postulates , Bohr radii measured the possible orbits for the electron and base that they are, as the squares of indwelling numbers game : 1:2:3: ... n The rate of n was called the star topology quantum number. The un iversal gas constant of the orbit proximate to the nucleus in a henry atom is 0.53 angstrom. The calculated frequency radiation hither attach to electron transitions from unmatchable orbit to an different(prenominal) , were only coincident with the frequencies found by experimentation for lines of total heat spectrum. and then was proved counteract figuring of enduring orbits, and with it the opportunity to withstand Bohrs postulates for such calculations. subsequent Bohrs theory was prolonged to the atomic structure of other elements, although this was receivable to some problems because of its novelty.
