Question 3 of 14 In 1910, Ernest Rutherford performed a set of experiments that helped scientists better understand the structure of atoms. He directed a beam of a particles (small, positively charged particles) at a very thin sheet of gold foil. He made several observations from the experiments. How did Rutherford interpret the fact that most of the a particles seemed to pass right through the foil? O Most of the volume of an atom is empty space so the a particles passed unobstructed through the electron clouds of the atoms. The foil was so thin that the a particles were able to pass in between the tiny, solid gold atoms. Gold is malleable so the gold atoms moved out of the way of the a particles and allowed them to pass through. How did Rutherford interpret the fact that a few of the a particles were deflected at very large angles? The a particles were striking the negatively charged electrons in the gold atoms. O The a particles were striking the neutrally charged neutrons in the…
