Which observation by Ernest Rutherford and his students refuted the plum pudding model?(1 point) Responses electron attraction electron attraction alpha particle deflection alpha particle deflection alpha particle attraction alpha particle attraction electron deflection

Answer 1

The observation by Ernest Rutherford and his students that refuted the plum pudding model was alpha particle deflection. This observation came from their gold foil experiment, where they found that some alpha particles were deflected at large angles, suggesting that there was a dense, positively charged nucleus in the atom, rather than a diffuse distribution of charge as proposed in the plum pudding model.
