Alpha particle scattering experiment class 11 and 12 In this experiment, a stream of particles from a radioactive source were directed onto a piece of gold foil that was extremely thin (less than 0.00004 cm thick). The alpha particles were predicted by Thomson's model to simply pass through the gold foil and be identified by a photographic plate positioned behind the foil. However, the experiment's real findings were extremely unexpected. According to observations: I The majority of the -particles cut through the gold foil unimpeded. (ii) A few of the -particles had minor angles of deflection. (iii) A few particles experienced sharp deflections. (iv) Approximately 1 in 12000 particles rebounded In 1911, Rutherford provided an explanation of the -ray scattering experiment's findings and put out a different atomic model. According to Rutherford's theory, an atom has a compact, positively charged region at its core that is known as the nucleus. The nucleus is where an atom
