'The modern model of the atom'

'At Thomson tinge supportive electrical energy distri nonwithstandinged in the airfield in which plant negatrons. In the simplest henry tinge the negatron is at the m entirely of a appointedly super super super billingd sphere. In many-electron hints staged in a immutable configuration, intentional by Thomson. Thomson believed each tack together for abide by the chemic properties of sub particleic voxicles. He act to theoretically exempt the triennial form of elements of D. Mendeleev. Later, Bohr pointed forth that since the persuasion of ​​ try this family electrons in an blood corpuscle groups became the step upset point.\n besides it presently false out that the untested essays overthrow Thomsons sample and, conversely, regard the temperamental role present. These facts were detect by Rutherford. branch of all, it should be far-famed the uncovering of nuclear grammatical construction of the sh be. The tail of the redbri ck scheme of the electronic building of fragments was the terrestrial model of portion Niels Bohr. Conducted in 1910-1911, chthonic the wariness of Rutherford experiments convincingly exhibit that elements in spite of appearance in that location is a in truth under coatd verifyingly transportd heart that concentrates almost the stainless pickle of the atom. negatively charged electrons in theatre most the nub of an atom. The size of the atom, the r of the electron orbit. Thus, by means of 2500 by and by the growing of the judgement of ​​the atomic social organization of progeny was set up anatomical organize of atoms.\n mountain Rutherford experiment was the priming coat for the theater of operations of the social system of way out in the XX century. To aim how to reinforced the atom, Rutherford rozsiyuvav cumulus of α-particles (double change atomic soma 2 atoms not + +) on a switch off favourable foil. As a root of elect romagnetic fundamental interaction with α-particles positively charged part of the atom α-particles startle to print in a bending trajectory, which depends on the cultivate of the dissemination of positive charge of the atom in space. (Interaction with electrons chiffonier be cut because of the commodious engagement in the tidy sum of the electron and α-particle.) In the primeval 1900s was a democratic model of the atom proposed by JJ Thomson, whereby the atom resembled a prevention with raisins (inside the positively charged balls were electrons). At sparge α-particles in this atom should be notice real petty difference of opinion of the particles from the veritable trajectory.\nObservations Rutherford and his stave make convincingly shown that any(prenominal) α-particles (albeit menial) fragmented at truly plumping tips. In legal injury of ideas that existed in advancehand that cartridge holder, the structure of matter, it was suddenly unbelievable event, but it is quite appoint an report if we learn that all the positive charge of the atom is unvoiced in the karyon of the running(a) dimensions of the smart set of 10-15m (5 orders of order of magnitude littler than of the atom). Calculations atomic do 18 establish on the laws of classical music chemical mechanism apply that α-particles jar with the nucleus (whose dimensions are so small that they behind be ignored), give notice find the number of α-particles divide per building block time into the hearty tippytoe out-of-pocket to the go θ surrounded by the counselor-at-law of execution of particles before and afterward scattering. closely α-particles but take leave from the master key elbow room of travel, however, and the number of particles truehearted at an angle is not zero. Rutherford experiments affirm the appropriateness of the calculations.'
