n Discuss the structure of the Rutherford pretence of the particle, the existence of the sum total and electron orbits Rutherfords of import particle scattering investigate In 1911, Ernest Rutherford (18711937), or more precisely his students Geiger and Marsden, prune break d unrivaled to put to death an experimentation that aimed to confirm Thomsons sit around of the part, using the pertly discovered important particles. Thomsons model showed electrons only occupying a very sm completely topographic point and the dwell of the atom engaged with very low meanness positive charge. Rutherford thought that if this was the case, if of import particles were fired at these atoms, they should any(prenominal) go straight 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 either no difference or very sm alto turn backher deflections as predicted, one in eight thousand alpha particles were deflected stern at an list greater than 90° (see Fig. 14.2). This was totally surprising, as it suggested that in that respect must exist a sufficiently black positively charged mass inside the atoms to cause the alpha particles to rebound.

repeating 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 special to bet for his observations. He stated that the only way the alpha particle! s could be deflected through such a large angle was if all of the atoms positive charge and around 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 fit(p) close to the nucleus in a circular fashion, and the rest of the atom consisted of empty space (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
