Rutherford

Ernest Rutherford was born in Nelson, New Zealand. Rutherford demonstrated his abilities as a scientist early on while working on his B.Sc. at the University of New Zealand in 1894. He showed that the magnetization can be removed from a magnetized iron needle by dissolving the surface layer of the metal in acid. He began work at Cambridge in 1895 and was a professor at the University of Manchester from 1907 on. It is during this time period that Rutherford made his most important discoveries. virtually to of Rutherfords work was piazzaed on radioactivity. He is the one who named the of import and beta particles. In 1911, Rutherford conducted his famous metallic foil experiment. He direct of import particles at a thin tack of gold foil and expected the particles to simply travel peachy by the foil. However, he obtained very different results. Although many of the particles did in event go cracking through the foil, some of them were deflected at double angles. Rutherfor d concluded that the deflections of the important particles were caused by a center of domineering charge that contained most of the atoms mass (the inwardness). He similarly explained that the particles that went straight through the foil did so because the atom is more oft than not empty space and that the distance between electrons and the nucleus is abundant compared to the size of the nucleus itself. In 1919, he sight the drippy tumult of north. His experiments show that under alpha radiation, nitrogen is decomposed and henry is formed.

Rutherford also devised an electrical method for counting the turn of ev ents of alpha particles emitted from radioac! tive substances. Using this method, he measured the act of alpha particles expelled per second from one gram of radium to be 34000. before Rutherford, the smallest particle of matter was represented as a strong ball. Rutherfords experiments with the decay of radioactive elements caused him to think in name of a more definite structure. He observed that the disintegration of elements was attended by emissions of positive helium and of negative particles of around no mass. He then concluded that an atom is not the remnant unit of matter, rather, it is composed of subatomic particles. If you want to come a full essay, order it on our website: OrderCustomPaper.com
