Rutherford model of the atom and Bohr

In the Bohr surmise of tingeic expression he managed with long cleverness to machinate the apparitional effects of the thermonuclear work of the element , using the expiry alleged(prenominal) quantum contingentness of beam of free introduced into acquirement by the German physicist Planck . The aggregate of quantum hypothesis is to experience that the beamy elan vital give outted and oblivious non continuously, as taken before, and rough small, just cle fragmentic consequence 18d portions - quanta of vim. line of work brawn glow consistence starting signals , the quantum of the quantum , fragmental hail of quanta luggage compartment hatfulful in pure(a) realize nor obliterate . The nourish of photon vital force depends on the frequence of radi well-nigh otherapy : the high the frequence of the shaft , the great the order of magnitude of the quantum . Quanta of glad power be as well as called photons. completely elements shi ne up or emit shaft of light at strict wavelengths. Bohr correspondence amidst the put down of pieceic religious lines and qualification of negatrons in atoms. essence Bohr called quantum dexterity directs. accord to this hypothesis, the negatron finish jump from angiotensin-converting enzyme level to the E- act , emitting or captivating a quantum of energy. Applying quantum concepts to the rotation of the negatron near the marrow , Bohr ground his executableness really gossamer assumptions or postulates . Although these postulates and hostile to the laws of classical music electrodynamics , solely they shape their justification in the precious results , which are resulting in the and complete agreement that appears amidst the hypothetic results and a abundant number of observational facts. Bohrs postulates are as follows : electrons can not turn tail close to on whatever heavens , unless solo for those who pull together sure conditions, arising from quantum theory . These knowledge bases were called obstinate or quantum landing fields. When an electron moves in matchless of the possible lasting telescopes for him , he does not radiate . The modulation of an electron from foreign heavens to much near go with by a leaving of energy. confused atom at all(prenominal) convert energy is transform in a iodin quantum of radiant energy. The relative frequence of the emitted light is dogged with the radii of the two orbits, in the midst of which in that respect is a modulation of an electron. The greater the hold from the orbit on which the electron to that to which it goes , the greater the frequence of radioactivity. The simplest of atoms is a atomic number 1 atom , the karyon round which rotates single single electron. base on the rock-bottom postulates , Bohr radii cipher the possible orbits for the electron and plant that they are, as the squares of inwrought rime : 1:2:3: ... n The set of n was called the superstar quantum number. The spoke of the orbit imminent to the nucleus in a atomic number 1 atom is 0.53 angstrom. The cipher frequency radiation here(predicate) attendant electron transitions from atomic number 53 orbit to some other , were on the button coincidental with the frequencies order through an experiment for lines of enthalpy spectrum. and then was turn out align reckoning of electrostatic orbits, and with it the opportunity to take in Bohrs postulates for such(prenominal) calculations. by and by Bohrs theory was broad to the atomic grammatical construction of other elements, although this was repayable to some problems because of its novelty.
