Answer:
The alpha scattering experiment done by Rutherford proved that an atom is not a bowl of positively charge atom, where the electrons were evenly spread out inside it like the plum pudding model. This is because Rutherford discovered that the atoms are mostly empty space with the aplha particles passing straight through the foil. However, a small number of the alpha particles were deflected and bounced back; meaning that the center of the atom is were the mass was mostly concentrated with a positive charge nucleus.
