WebFig. 4.2: Scattering of α-particles by a gold foil But, the α-particle scattering experiment gave totally unexpected results (Fig. 4.2). The following observations were made: (i) Most of the fast moving α-particles passed straight through the gold foil. (ii) Some of the α-particles were deflected by the foil by small angles.

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny, heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. Rutherford presented his own …
WebVerified by Toppr. Three major observations Rutherford made in the gold foil experiment are. 1.Almost all the alpha particles did pass through the foil. 2.Some alpha particles were deflected off at different angles as observed at the screen of the detector. 3.Very few of the alpha particles (one or two) even bounced backwards after hitting the ...
