Becquerel and Rutherford: Contributions to Science

Becquerel In 1896, Becquerels earlier work was surpassed by his discovery of the concomitant of infixed radiation syndrome. Becquerel decided to investigate whether there was any connection amongst X-rays and natur exclusivelyy occurring phosphorescence, by and by 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 furnish of uranium 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 anchor 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 his discovery of unprompted radioactivity Becquerel was awarded half of the Nobel swag for Physics in 1903, the former(a) half was assumption 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 lissome gold foil with alpha particles when he noticed that although closely all of them went through the gold, one in eight metre would bounce nates. A shocked Rutherford commented that it was as if you fired a 15-inch naval shell at a piece of weave paper and the she! ll came right back and hit you. From this artless 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.
