Best answer
  • Rutherford bombarded a thin gold foil with a stream of fast moving α – particles. 
  • It was observed that most of the α-particles passed through the foil. 
  • Some of them were deflected through a small angle. 
  • Very few α- particles were reflected back by 180°. 
  • Based on these observations, he proposed that in an atom, there is a tiny positively charged nucleus and the electrons are moving around the nucleus with high speed.
