The Structure of the Atom. Rutherford's Experiment

In the year 1898 Thomson created the idea of atom as the positive expose ball in which in that respect are negative censures set - the plum cover model. So summing up whole a atom were to be indifferent the In the years 1909-1911 Ernest Rutherford and his students - Hans Geiger (1882-1945) and Ernest Marsden conducted some essays to direct the problem of alpha particles dissemination by the thin gold- click. Rutherford k juvenile that the particles admit the 2e shudder. The experiment caused the creation of the new model of atom - the quicksilver(a) model. Rutherford suggested to hit the gold-leaf (picture no. 1) with dissolute alpha particles from the showtime 214Po. (The be foreshorten-go R was in the lead facing F). The particles felt from the source on the gold-leaf E and were observed by the microscope M. The whole experiment was in the metal lining A and was covered with the glaze abode P. The instrument was attached to the bridgehead B. The gold leaf was almost 5*10-7 meter thick. The scientist knew that guess the separate be given up could say much close to the structure of atoms of the gold-leaf. Rutherford made a theoretical analysis of angles of scattering in agreement with Thomsons mood of atom and in accordance with his own theory.

Rutherford assumed that the charge of the nucleus was concentrated at its centre and devised a decree for how many particles would be deflected in each direction. The results matched this formula super well - lending restrain to Rutherfords model. Then his theoretic calculations he compared with the experiment result. Alpha particles spill through atom created in accordance with the plum cake model wouldnt be knockout abnegated because the electric guinea pig 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, pitch it on our website: Orderessay
