In the early 1900s, Ernest Rutherford produceda beam of very small positive particles and directed it at a thinpiece of gold foil just a few atoms thick. Most of the particlespassed through the foil without changing their path; very rarely, aparticle was deflected. What conclusions can you draw from thisexperiment about the structure of an atom?
