Rutherford Gold Foil Experiment - Backstage Science [360p | 2K]

A detector that would flash when hit by an alpha particle. The Unexpected Result

While most did pass through, Rutherford was shocked to find that: Rutherford Gold Foil Experiment - Backstage Science

To look inside the atom, Rutherford needed to fire something at it. He used: A detector that would flash when hit by an alpha particle

At the time, scientists believed in the , where an atom was a blob of positive charge with electrons scattered inside like fruit in a pudding. If this were true, the heavy alpha particles should have whizzed straight through the "soft" atoms. If this were true, the heavy alpha particles

In 1911, Ernest Rutherford and his team (Hans Geiger and Ernest Marsden) conducted the "Gold Foil" experiment, which Backstage Science describes as essentially the .

Positively charged particles emitted from a radioactive source (radium).
