Rutherford’s gold foil experimentRutherford’s gold foil experiment


• Video! Rutherford’s Gold Foil Experiment


• In Rutherford's experiment, a radioactive source shot a stream of alpha particles at a sheet of very thin gold foil which stood in front of a screen. The alpha particles would make little flashes of light where they hit the screen.


• Since some of the positive alpha particles were substantially deflected,


• Since some of the positive alpha particles were substantially deflected, Rutherford concluded that there must be something inside an atom for the alpha particles to bounce off of,


• Since some of the positive alpha particles were substantially deflected, Rutherford concluded that there must be something inside an atom for the alpha particles to bounce off of, that must be small, dense, and positively charged.
