Ernest Rutherford

Ernest Rutherford was born in New Zealand in 1871 as maven of 12 children. It was Rutherford who first split an mite and who discovered the atomic nucleus, a name that he invented. For this he is regarded as the greatest experimental physicist of his time. Rutherford was virtuoso of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of beam. By covering his Uranium with thin foils of aluminum, gradually increasing the crook of foils. For the first three layers of foil the radiation escaping from the uranium lessen progressively, suggesting an ordinary law of absorption. More thickness of aluminum, however, had little raise effect in reducing the radiation at first, hardly eventually the intensity of the radiation began to diminish again as even more foils were added. These experiments showed that there were at least ii distinct types of radiation- one that is very readily absorbed, which he called the of import - radiation, and the other more penetrative character which he called the of import - radiation. He also had believed that he had found a troika more penetrating radiation. The Frenchman, Paul Villard, officially gave this third radiation.



He named it, after Rutherfords first two radiation discoveries, the gamma- radiation. It was these discoveries in radiation that opened the door to the rest of Rutherford discoveries. Using this alpha radiation, Rutherford started to experiment putting it through other materials to get the effects. It was in one of these experiments with gilt that he was able to figure out what an atom looks like. He found that a countable number of alpha particles actually bounced back from a thin sheet of gold foil. Of course the majority of the particles went straight through the gold and were but slightly scattered. Rutherford said that this was the most surprising result he had known....If you want to get a full essay, order it on our website: Ordercustompaper.com
