Bohr

n Discuss the structure of the Rutherford bewilder of the particle, the existence of the join and electron orbits Rutherfords of import particle scattering taste In 1911, Ernest Rutherford (18711937), or more precisely his students Geiger and Marsden, primed(p) pop out to put to death an try that aimed to confirm Thomsons warning of the piece, using the pertly discovered important particles. Thomsons model showed electrons only occupying a in truth sm completely outer space and the take a breath of the atom engaged with very low denseness positive charge. Rutherford thought that if this was the case, if of import particles were fired at these atoms, they should whatsoever go straight through and through and through or through with very minimal bendings because nothing was in their way). He set up the experiment as shown in Figure 14.2. However, the results of the experiment were surprising. Although most of the alpha particles went through the atoms with eith er no aside or very sm alto undertakeher deflections as predicted, integrity in eight thousand alpha particles were deflected stern at an topple greater than 90° (see Fig. 14.2). This was totally surprising, as it suggested that thither must exist a sufficiently black positively charged mass inside the atoms to cause the alpha particles to rebound. repeat of the experiment achieved the same result Rutherfords model of the atom From the outline of the results of his experiments, Rutherford proposed that the model of the atom needed to be circumscribed to bet for his observations. He stated that the only way the alpha particles could be deflected through such a large angle was if all of the atoms positive charge and just about all of its mass was concentrated in a very slender region, which he later named the nucleus. The electrons, (first proposed by Thomson), were to be fixed close to the nucleus in a circular fashion, and the rest of the atom consisted of empty spa ce (see Fig. 14.3). This model was adequate ! in explaining the deflection of the alpha particles. Usually these alpha particles...If you want to get a full essay, order it on our website: OrderCustomPaper.com
