Sir James Chadwick, CH (October 20, 1891 – July 24, 1974) was an English physicist and Nobel laureate who is best known for discovering the neutron.This discovery transformed subatomic physics and enabled scientists to produce new elements. It also led to the discovery of nuclear fission and its uses for both war and peace.
James Chadwick foi um físico britânico que teve um papel fundamental na evolução do modelo atômico. Ele é mais conhecido por sua descoberta do nêutron em 1932, o que revolucionou a compreensão da estrutura do átomo. Antes da sua descoberta, acreditava-se que o núcleo atômico era composto apenas por prótons e elétrons.
James Chadwick at the 1933 Solvay Conference. Chadwick had discovered the neutron the year before while working at Cavendish Laboratory.. The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century. Early in the century, Ernest Rutherford developed a crude model of the atom,: 188 based on the gold foil ...
James Chadwick was born on October 20, 1891, in Cheshire, England. He graduated from Manchester University's Honours School of Physics in 1911 and spent the next two years working on various radioactivity problems in the Physical Laboratory in Manchester, earning a M.Sc. degree in 1913 as well as the 1851 Exhibition Scholarship, which allowed him to continue his research and move to Berlin to ...
But Chadwick's origins 20 miles away never indicated what he would later achieve. "He was not from any kind of wealthy background," says Dr James Sumner, a historian of technology at the ...
James Chadwick realizó varias contribuciones significativas a este campo de la física, las cuales explicaremos a continuación. Desarrollo del Modelo de Núcleo Atómico En la década de 1930, Chadwick trabajó en el desarrollo del modelo de núcleo atómico, el cual explicaba cómo los protones y neutrones se mantienen juntos en el núcleo atómico.
James Chadwick (Bollington, 20 oktober 1891 – Cambridge, 24 juli 1974) was een Brits natuurkundige. In 1932 ontdekte hij het neutron, een elementair deeltje zonder elektrische lading in de kernen van alle atomen uitgezonderd waterstof, in haar meest voorkomende isotoop.
