Answer the following questions given below:
A group of scientists conducted an experiment to study the structure of the atom. They directed a beam of fast-moving alpha particles toward a very thin sheet of metal foil. The experiment helped scientists understand the arrangement of particles inside the atom and showed that the earlier atomic model proposed by J. J. Thomson could not fully explain the observations.
1. Which scientists performed this experiment under the guidance of Ernest Rutherford?
2. The particles used in the experiment were:
3. Thomson’s model failed because it could not explain:
