Rutherford was interested in knowing the structure of an atom so he took a gold foil and did the alpha scattering experiments.
he observed that:
many of the fast moving alpha rays passed straight which means most of the space is empty
many other rays were reflected by small angles
many of one rebound which means that there is a very small nucleus in the center
his drawback:
he could not explain the stability of an atom

Hey!!!
Rutherford was curious to know about the structure of atom. So he took gold foil because it is highly malleable and bombarded alpha particles on it. He was assuming that most of the particles will deflect back. But the outcome was something else. Most of the particles passed through it, some particles only reflected back through some angles and only one particle was deflected by 180 degree. So Rutherford concluded from this that in an atom the protons are present in the centre, in the nucleus, and electrons move around it. The drawback was that if the electrons will move continuously then at some point of time they will gain acceleration and will fall in the nucleus. But if this would happen then matter would not be present in the form in which it is present now. It would be unstable.
Hope it helps!
