Give the salient features of Rutherford’s Nuclear Model of atom.

Answer»

Rutherford conducted alpha scattering experiment and put forward a model of atom known as Rutherford’s nuclear model.

The salient features of this model are as follows:

  • The atom of an element consists of a small, positively charged nucleus in the centre, which carries almost the entire mass of the atom.
  • The electrons are revolving around the nucleus at high speed.
  • The number of electrons in an atom is equal to the number of protons. Hence it is electrically neutral.
  • The volume of the nucleus is negligibly small compared to the volume of the atom.
  • Most of the space in the atom is empty.
