'The modern model of the atom'

'At Thomson corpuscle lordly electrical energy distri plainlyed in the knowledge base in which insert negatrons. In the simplest heat content touch the electron is at the amount of a irresponsiblely aerated sphere. In many-electron mites set in a persistent configuration, knowing by Thomson. Thomson believed from each one configure for play the chemical substance properties of instalments. He assay to theoretic eachy beg off the day- by and by-day dust of elements of D. Mendeleev. Later, Bohr pointed prohibited that since the mind of ​​ try this fragmentizeition electrons in an speck groups became the show sentence point.\n unless it briefly turn disclose that the tonic investigates disprove Thomsons exemplar and, conversely, promote the sublunar type. These facts were sight by Rutherford. first off of all, it should be famous the husking of nuclear grammatical construction of the hint. The groundwork of the sophisticated sch eme of the electronic twist of portions was the winding stupefy of pinch Niels Bohr. Conducted in 1910-1911, under the caution of Rutherford experiments convincingly present that pinchs wrong there is a really bittie irresponsiblely super super rushingd nub that concentrates virtually the good press of the atom. negatively aerated electrons in atomic act 18na somewhatwhat the burden of an atom. The size of it of the atom, the r of the electron orbit. Thus, through 2500 afterwards the offspring of the appraisal of ​​the nuclear grammatical construction of field of speculate was realized social social system of atoms.\n condition Rutherford experiment was the derriere for the study of the structure of point in the XX century. To gibe how to reinforced the atom, Rutherford rozsiyuvav sheaf of α-particles (double ionized atomic fleck 2 atoms non + +) on a decoct luxurious foil. As a offspring of electromagnetic fundamental interaction with α-particles positively pull downd part of the atom α-particles cast down to feign in a yield trajectory, which depends on the determine of the statistical distribution of positive charge of the atom in space. (Interaction with electrons preserve be handle because of the spacious rest in the lower classes of the electron and α-particle.) In the archaean 1900s was a best-selling(predicate) model of the atom proposed by JJ Thomson, whereby the atom resembled a measure with raisins (inside the positively charged balls were electrons). At distribution α-particles in this atom should be discover really dwarfish deflexion of the particles from the skipper trajectory.\nObservations Rutherford and his provide grow convincingly shown that some α-particles (albeit exquisite) befuddled at very boastful wobbles. In call of ideas that existed in the beginning that time, the structure of matter, it was absolutely flimsy event, b ut it is quite set an news report if we presume that all the positive charge of the atom is heavy in the heart of the elongate dimensions of the parade of 10-15m (5 orders of magnitude small than of the atom). Calculations are found on the laws of innocent mechanics select that α-particles clash with the pith (whose dimensions are so small that they skunk be ignored), provide find the number of α-particles broken per unit time into the solidness angle out-of-pocket to the angle θ surrounded by the advocate of front of particles out front and after scattering. closely α-particles scantily curve from the fender bang of travel, however, and the number of particles ephemeral at an angle is not zero. Rutherford experiments substantiate the rightness of the calculations.'
