Any one of U have the dot point on Rutherford's experiment that led to his model of atom???
Is that the one with scattering Alpha particle and he showed that a thin sheet of mica deflect the alpha ray?
Oui, as a result of the experiment the guy decided that the atom must be made up of a dense +ve nucleus (hense the deflections) and also is surrounded by electrons, which is y most alpha particles passed through.
