![]() Therefore, he concluded that the positively charged particles covered a small volume of an atom in comparison to the total volume of an atom. Moreover, very few particles had deflected at 180 o. Very few α-particles had deflected at large angles or deflected back.They were deflected minutely and at very small angles. The positive charge in an atom is not distributed uniformly and it is concentrated in a very small volume – Few α-particles when bombarded were deflected by the gold sheet.Therefore, the major part of an atom must be empty. Major space in an atom is empty – A large fraction of α-particles passed through the gold sheet without getting deflected.On the basis of the observations made during the experiment, Rutherford concluded that Rutherford’s Gold Foil Experiment (Source Credit: Britannica) Observations of Rutherford Model Experiment The observations made by Rutherford contradicted the plum pudding model given by J.J. To study the deflection, he placed a screen made up of zinc sulfide around the gold foil. He conducted the experiment to study the deflection produced in the trajectory of α-particles after interaction with the thin sheet of gold. The streams of α-particles were directed from a radioactive source. In Rutherford’s experiment, he bombarded high energy streams of α-particles on a thin gold foil of 100 nm thickness. ![]()
