In the year 1898 Thomson created the idea of corpuscle as the appointed aerated ball in which there are banish censures located - the plum cake fabric. So summing up totally a atom were to be neutral the In the days 1909-1911 Ernest Rutherford and his students - Hans Geiger (1882-1945) and Ernest Marsden conducted some essays to calculate the problem of alpha particles dissemination by the thin silver- click. Rutherford knew that the particles halt the 2e charge. The experiment caused the creation of the new put 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 mat from the source on the gold-leaf E and were observed by the microscope M. The unit of measurement 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 about 5*10-7 meter thick . The scientist knew that reckoning the scattering be given could say frequently about the social organisation 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 induce theory.
Rutherford assumed that the charge of the nucleus was concentrated at its essence and devised a rule for how many particles would be deflected in individually direction. The results matched this formula extremely well - lending support to Rutherfords model. consequently his theoretic calculations he compared with the e xperiment result. Alpha particles going wit! h 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:
