Becquerel and Rutherford: Contributions to Science

Becquerel In 1896, Becquerels earlier work was surpassed by his discovery of the accompaniment of infixed radiation. Becquerel decided to investigate whether there was any connection amongst X-rays and natur exclusivelyy occurring phosphorescence, after his discussion with Henri Poincaré on the radiation which had been latterly discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum tube. He had inherited from his obtain a add up of uracil salts, which exhibits phosphorescence upon exposure to light. When the salts were placed show up to a photographic carapace covered with opaque paper, the plate was implant to be fogged. The phenomenon was found to be common to all the uranium salts studied and was concluded 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 electric or magnetic fields. For h is discovery of unprompted radioactivity Becquerel was awarded half of the Nobel swag for Physics in 1903, the former(a) half was addicted to Pierre and Marie Curie for their study of Becquerels radiation. Rutherford Rutherford was awarded the Nobel Prize for his ground-breaking work in nuclear physics. In 1909, while at the University of Manchester, Rutherford overran a rationalise gold foil with alpha particles when he noticed that although nigh all of them went through the gold, one in eight kibibyte would bounce nates. A shocked Rutherford commented that it was as if you fired a 15-inch naval shell at a piece of create from raw material paper and the shell came right back and hit you. From this guileless observation, Rutherford concluded that the atoms mass must be concentrated in a tiny, positively-charged nucleus, while the electrons occupy the farthest ranges of the atom.
