Detailed Solution

After bombarding α-particles through a gold foil, Rutherford observed that most of the fast-moving α- particles passed straight through the gold foil. Some α-particles were observed to be deflected by the foil by small angles. Very few α-particles (one out of 12000) were observed to rebound.

Most alpha particles passed straight through the gold foil, which implied that atoms are mostly composed of open space. Some alpha particles were deflected slightly, suggesting interactions with other positively charged particles within the atom.
