Thomson rutherford and bohr model of atom

WebThe atomic theory was further expanded in 1911 when Thomson's colleague Ernest Rutherford began experimenting with alpha particles to probe the atomic structure of gold foil. In his now-famous Gold Foil Experiment, Rutherford saw that while most alpha particles passed right through the gold foil, a few deflected to the side, and some even bounced back. WebIn atomic physics, the Bohr model or Rutherford–Bohr model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913, consists of a small, dense nucleus surrounded by orbiting electrons.It is analogous to the structure of the Solar System, but with attraction provided by electrostatic force rather than gravity.In the history of atomic physics, it …
