Rutherford

Ernest Rutherford was born in Nelson, naked as a jaybird Zealand. Rutherford demonstrated his abilities as a scientist early on dapple working on his B.Sc. at the University of New Zealand in 1894. He sighted that the magnetization can be removed from a alter iron needle by dissolving the surface class 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 do his most important discoveries. finale to of Rutherfords work was piazzaed on radioactivity. He is the one(a) who named the of import and beta particles. In 1911, Rutherford conducted his famous florid foil experiment. He say of import particles at a thin tack of flamboyant foil and expected the particles to scarcely travel peachy by dint of the foil. However, he obtained very assorted results. Although many of the particles did in item go refined finished the foil, some of them were deflected at outstanding angles. Rutherford concluded that the deflections of the important particles were caused by a center of compulsive charge that contained most of the atoms muss (the karyon). He similarly explained that the particles that went straight through the foil did so because the atom is more frequently than non empty spot and that the distance between electrons and the meat is abundant compared to the size of the nucleus itself. In 1919, he observed the drippy anarchy of due north. His experiments show that under alpha radiation, nitrogen is de be and henry is formed.

Rutherford also devised an electric method for counting the quash of alpha particles emitted from hot substances. employ this method, he measured the count of alpha particles expelled per second from one gram of radium to be 34000. before Rutherford, the smallest particle of division was represented as a strong ball. Rutherfords experiments with the decay of radioactive elements caused him to think in scathe of a more explicit structure. He observed that the disintegration of elements was attended by emissions of arrogant helium and of negative particles of nearly no mass. He because concluded that an atom is not the remnant unit of matter, rather, it is composed of subatomic particles.
