Question

Quizplus · Accepted Answer

Rutherford's experiments showed that most of the alpha particles passed through the gold foil, indicating that atoms are mostly empty space. However, a small fraction of alpha particles were deflected back, indicating the presence of a dense, positively charged nucleus. Therefore, based on these experiments, Rutherford proposed that most of the mass of atoms is located in a dense, small volume nucleus that is positively charged. Hence, all the options (A, B, and C) are correct, making the answer D.
