Question.
Compare all the proposed models of an atom given in this chapter.
Thomson’s model
Rutherford’s model
Bohr’s model

Solution:
An atom consists of a positively charged sphere with electrons embedded in it.
An atom consists of a positively charged particles concentrated at the centre known as the nucleus. The size of the nucleus is very small as compared to the size of the atom. The electrons revolve around the nucleus in well-defined orbits.
There are only certain orbits known as discrete orbits inside the atom in which electrons revolve around the nucleus. Electrons do not radiate energy while revolving.
