"WebKey Concepts and Summary. 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 through, were deflected slightly or significantly. Because most of the α particles passed through undeflected, Rutherford deduced that the atom was mostly empty space. " - Robert gold foil experiment
