Homework Help: Rutherford's experiment alpha source

  1. Jan 25, 2010 #1
    Rutherford investigated the scattering of alpha particles by gold foil in an evacuated container. The evidence from his investigations led to the nuclear model of the atom.

    Why was it important for this investigation that the alpha source was inside the container?

    Rutherford wanted to see how the alpha particles were deflected by the gold atoms. If there were other atoms between the alpha particles and the gold atoms, how would he know that the gold atoms were causing the deflection of the alpha particles that he observed?
