One of the observations during α-particle scattering is that most of the fast moving α-particles passed straight through the gold foil non-deviated. What does this observation explain?

Expert Answer:

Most of the space around the nucleus is empty which allows the alpha particles to pass through them non-deviated. The nucleus is very small in size and is located at the centre of the atom and hence very few alpha particles deflected by an angle of 180o.
