Becquerel and Rutherford: Contributions to Science

Becquerel In 1896, Becquerels earlier work was surpassed by his discovery of the situation of infixed radioactivity. Becquerel decided to investigate whether there was any connection amongst X-rays and natur exclusivelyy occurring phosphorescence, later 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 come forth of atomic number 92 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 lay down to be fogged. The phenomenon was found to be common to all the uracil 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 his discovery of unprompted radioactivity Becquerel was awarded half of the Nobel swag for Physics in 1903, the former(a) half was condition 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 dainty gold foil with alpha particles when he noticed that although or so all of them went through the gold, one in eight kilobyte would bounce nates. A shocked Rutherford commented that it was as if you fired a 15-inch naval s hell at a piece of tissue paper paper and th! e shell came right back and hit you. From this candid 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.
