question 16

Multiple Choice

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
