Observation of Rutherford model

Dear Student,

1.The major observations of the Rutherford atomic model are as follows.

  • All protons are present inside the nucleus, which is situated at the centre of the atom.
  • Electrons reside outside the nucleus and revolve around the nucleus in well-defined orbits.
  • The size of the nucleus is very small in comparison to the size of an atom. As per Rutherfords calculations, the size of the nucleus is 105 times smaller than an atom.
  • As the mass of the electron is negligible in comparison to the mass of the proton, almost all the mass of the atom is concentrated in the nucleus.

The observations made by Rutherford led him to conclude that: A major fraction of the α-particles bombarded towards the gold sheet passed through it without any deflection, and hence most of the space in an atom is empty. Some of the α-particles were deflected by the gold sheet by very small angles, and hence the positive charge in an atom is not uniformly distributed. The positive charge in an atom is concentrated in a very small volume. Very few of the α-particles were deflected back, that is only a few α-particles had nearly 180o angle of deflection. So the volume occupied by the positively charged particles in an atom is very small as compared to the total volume of an atom.
