Question 3 • 26-27 - C - RUSD Chemistry in the Earth System
Rutherford’s gold-foil experiment showed that most alpha particles passed through the foil, while a few were sharply deflected. This indicated that an atom is mostly empty space with a small, dense, positively charged nucleus, leading to the nuclear model. The plum pudding model was proposed by J. J. Thomson, not established by Rutherford’s experiment.
