- 1What is the gold foil experiment?Where alpha particles are fired at a thin sheet of gold foil (one atom thick) and the scattering of alpha particles is observed.
- 2Who conducted the first gold foil experiment?Ernest Rutherford and his two students, Hans Geiger and Ernest Marsden.
- 3What did Rutherford prove with the gold foil experiment?That the atom had a positively charged nucleus.
- 4What are the 3 observations of the Gold Foil Experiment?Most of the alpha particles passed straight through.
Some of the alpha particles deflected slightly at an angle less than 90°.
Very few alpha particles deflected at angle between 90° and 180°.
