How the presense of nuckeus is proved by rutherford,s experiment of gold foil.?please anawer.. |
| Answer» ORD's model of an atom :Ernest RUTHERFORD was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil.He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick.α-particles are doubly-charged helium IONS. SINCE they have a mass of 4µ, the fast-moving α-particles have a considerable amount of energy. It was expected that α-particles would be deflected by the sub-atomic particles in the gold atoms. Since the α-particles were much heavier than the protons, he did not expect to see large deflections. But, the α-particle scattering experiment gave totally unexpected results .Observations of Rutherford's scattering experiment:As we can see in Fig. 1.Most of the fast moving α-particles passed straight through the gold foil.Some of the α-particles were deflected by the foil by small angles.Surprisingly one out of every 12,000 alpha particles appeared to rebound.I hope this answer is helpful to u...❤❤❤Keep Asking... ✌️✌️✌️✨✨✨If HELP u. Mark my answer as brainliest✨✨✨❤️❤️❤️Thank You❤️❤️❤️. | |
