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. nasty to of Rutherfords work was piazzaed on radioactivity. He is the one who named the of import and of import particles. In 1911, Rutherford conducted his famous notes foil experiment. He say of import particles at a thin tack of gold foil and expected the particles to simply travel peachy with the foil. However, he obtained very different results. Although many of the particles did in event go true through the foil, some of them were deflected at macro angles. Rutherford concl uded that the deflections of the important particles were caused by a center of ordained charge that contained most of the atoms mass (the heart and soul). He similarly explained that the particles that went straight through the foil did so because the atom is more often 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 notice the drippy chemical decomposition reaction of newton. His experiments show that under alpha radiation, nitrogen is decomposed and henry is formed.

Rutherford also devised an electrical met hod for counting the chassis of alpha parti! cles emitted from radioactive substances. Using this method, he measured the human activity 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 damage of a more definite structure. He observed that the disintegration of elements was attended by emissions of positive helium and of negative particles of near 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 bear a full essay, order it on our website: BestEssayCheap.com
