So, this is all about the Rutherford Model of Atom. Therefore he concluded that there must be the existence of a denser part in the atom with which the alpha particles collided and got back to their starting point. In this experiment rutherford constantly bombarded alpha particles on a gold foil which was very thin in nature. He along with Hans Geiger and Ernest Marsden conducted the Gold foil experiment. After the genesis of this idea, many philosophers and scientists gave their own version of Atomic theory. Preparation for the upcoming competitive exams like JEE Main, BITSAT, VITEEE, etc. i really recommended the site, thanks. When Rutherford's coworkers bombarded gold foil with particles, they obtained results that overturned the existing (Thomson) model of the atom. The third observation made was that only very few alpha particle rays were deflected back at 180. A . Rutherford developed a nuclear model of the atom on the basis of his experiment and observations. Analyzing a series of such experiments in detail, Rutherford drew two conclusions: The volume occupied by an atom must consist of a large amount of empty space. According to the accepted atomic model, in which an atom's mass and charge are uniformly distributed throughout the atom, the scientists . (ii) A small fraction of -particles were deflected through small angles, and a few through larger angles. Check out the other topics of Chemistry, here. In 1905, Ernest Rutherford did an experiment to test the plum pudding model. J.J. Thomson was the first to discover the subatomic particle called electron in 1904.

The scattered particles were detected by the fluorescent screen which emitted fluorescent spikes. It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field. But this is not possible because atoms are stable. An Atom is mainly empty inside. Based wholly on classical physics, the Rutherford model itself was superseded in a few years by the Bohr atomic model, which incorporated some early quantum theory. According to the Rutherfordatomic model: Although the Rutherfordatomic model was based on experimental observations, it failed to explain certain things. (i) Most of the -particle passed through the foil straight without suffering any change in their direction. Therefore the existence of electrons is also proved by this observation. The experiment was based on the scattering of alpha particles due to the presence of a gold foil. Some of the - particles suffered deflection by 90 or even larger angels. The scientist Ernest Rutherford realised that the only way to explain results from experiments by Geiger and Marsden was with a new model of the atom. His idea was to probe the structure of Atom by firing -particles or helium ions, at thin metal foils (Gold Foil). Rutherford observed that most of the alpha particles passed straight through the gold foil, while some of them were deflected by a small angle, and a very few rebounded. However, many scientists around the world proved this theory to be wrong.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'electricalfundablog_com-medrectangle-4','ezslot_13',615,'0','0'])};__ez_fad_position('div-gpt-ad-electricalfundablog_com-medrectangle-4-0'); In 1911, Rutherford, Geiger and Marsden performed the Gold Foil experiment, also called Geiger-Marsden experiment which was a breakthrough in the field of chemistry. The idea was even lost for a few centuries and was rediscovered by John Dalton at the end of the 18th century. He also stated that negatively charged particles rotate around the nucleus, and there is an electrostatic force of attraction between them. In 1904, Thomson proposed the "plum pudding" model of atoms, which described a positively charged mass with an equal amount of negative charge in the form of electrons embedded in it, since all atoms are electrically neutral. As per Rutherfords model, electrons revolve around the nucleus in a circular path. He took 0.00004cm thick gold foil, on which alpha particles were bombarded.
