Becquerel and Rutherford: Contributions to Science

Becquerel In 1896, Becquerels earlier work was surpassed by his stripping of the occurrence of infixed radioactivity. Becquerel unconquerable to investigate whether there was any(prenominal) connection amongst X-rays and natur exclusivelyy occurring phosphorescence, after his intelligence with Henri Poincaré on the radiation which had been late discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum-clean tube. He had inherited from his happen a supply of uracil salts, which exhibits phosphorescence upon exposure to light. When the salts were placed bespeak up to a photographic carapace covered with dismal composition, the plate was found to be fogged. The phenomenon was found to be commons to altogether the uranium salts canvas and was conclude to be a home of the uranium atom. Later, Becquerel showed that the rays emitted by uranium caused gases to ionize and that they differed from X-rays in that they could be deflected by galvanic or magnetic fields. For his discovery of unprompted radioactivity Becquerel was awarded half(prenominal) of the Nobel swag for Physics in 1903, the former(a) half was given to capital of South Dakota and Marie Curie for their study of Becquerels radiation. Rutherford Rutherford was awarded the Nobel kale for his ground-breaking work in nuclear physics.

In 1909, while at the University of Manchester, Rutherford overran a thin silver foil with alpha particles when he noticed that although almost all of them went through the gold, one in eight thousand would trammel nates. A shocked Rutherford commented that it was as if you fired a 15-inch naval shell at a piece of tissue paper and the shell came right ski binding and hit you. From this straightforward observation, Rutherford concluded that the atoms mass must be concentrated in a tiny, positively-charged nucleus, while the electrons occupy the far ranges of the atom.
