45. In 1911 Ernest Rutherford did a famous experiment using fast-moving alpha particles as bullets and very thin gold foil as a target. The results of this experiment showed that: a. the negative and positive charges were all spread out throughout the volume of each atom b. that the absorption spectrum of gold atoms had more lines than scientists could explain c. that alpha particles were neutral (demonstrating the existence of neutrons) d. that the nucleus of an atom was tiny compared to the size of the whole atom e. it was far better to use cheaper materials than gold for physics experiments
