Rutherford’s famous gold foil experiment was performed by aiming α particles at a sheet of gold foil and observing whether the α particles passed …
WebRutherford conducted an experiment by bombarding a thin sheet of gold with α-particles and then studied the trajectory of these particles after their interaction with the gold foil. Rutherford, in his experiment, directed high energy streams of α-particles from a radioactive source at a thin sheet (100 nm thickness) of gold. Webb) The Millikan "oil drop" experiment was able to determine the charge of an electron. c) Rutherford's "gold foil experiment" established that atoms are mostly empty space. d) Thomson determined the charge to mass ratio of electrons in his cathode ray tube experiments. 11.
