1. RUTHERFORD’S EXPERIMENT Name-Shrabani Kerketta Class-8 Roll nimber - 35

2. What was the experiment ? He performed a experiment by bombarding a thin gold foil with very small and positive charged particles called alpha particles.

3. Observations Most of the alpha particles pass through the gold foil . Some alpha particles showrd small deviation from theor path. A very very small number of aplha particles reboundead to their original path.

4. Based on these observations,Rutherford put forward the new model of an atom. The atom is almost empty from within,such that the size of a nucleus is almost negligible. The electrons revolve arounf the nucles at a very high speed. In an atom,the number of protons is always equal to the number of electrons.
