what are observation inference of ruderford model of atom ?
In Rutherford's Model ;
Rutherford bombarded a thin gold foil with radioactive rays ( α-particles) and a ZnS screen was placed in back of the gold file so that when the particles strike to the foil some of them get scattered and produced a glow on the ZnS screen.
The phenomena was monitored by a microscope and the observations obtained were:
1. Almost all of the α-particles passed through the metal and remain un deflected.
2. Some of the α-particles deflected through a very small angles.
3. Very few of them deflected through 1800.
So, the conclusions or inferences obtained were:
1. Since, almost all particles passed un deflected so the space inside the atom is empty, and large deflection by some particles show that show existence of positively charged inside the body of atom which repelled the +ve charged α-particles.
2.Since, deflection was very few means, that the nucleus takes very small space or volume inside atom.
3. Only a small fraction of particles underwent a 1800 deflection. This shows that the entire positive charge and mass of an atom are present within a very small volume inside the atom.
