What are the conclusions of Rutherford’s α – rays scattering experiment?
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.
