In the year 1898 Thomson created the idea of instalment as the positivistic aerated ball in which there are minus censures located - the plum cake theoretical account. So summing up full-length a atom were to be neutral the In the years 1909-1911 Ernest Rutherford and his students - Hans Geiger (1882-1945) and Ernest Marsden conducted some essays to calculate the problem of of import particles break up by the thin bullion- click. Rutherford knew that the particles halt the 2e charge. The experiment caused the creation of the new pretence of atom - the fickle model. Rutherford suggested to hit the gold-leaf (picture no. 1) with fast alpha particles from the showtime 214Po. (The beget-go R was in the lead lining F). The particles matte from the source on the gold-leaf E and were observed by the microscope M. The all in all experiment was in the metal lining A and was cover with the glaze plate P. The instrument was attached to the footing B. The gold leaf was abou t 5*10-7 meter thick. The scientist knew that reckoning the scattering be given could say a great deal about the anatomical structure of atoms of the gold-leaf. Rutherford made a theoretical analysis of angles of scattering in accordance with Thomsons supposition of atom and in accordance with his accept theory.
Rutherford assumed that the charge of the nucleus was concentrated at its burden and devised a rule for how many particles would be deflected in severally direction. The results matched this formula extremely well - lending support to Rutherfords model. thusly his theoretic calculations he compar ed with the experiment result. Alpha particl! es going with atom created in accordance with the plum cake model wouldnt be voiceless abnegated because the electric field in that atom wouldnt be strong. In the model created by Rutherford the field is much stronger near... If you want to get a full essay, order it on our website:
