Structure of Atom


What are the limitations of J.J. Thomson’s model of the atom?


J.J Thomson gave the first model for the structure of an atom. According to his model, the atoms consist of a positively charged sphere in which the electrons are embedded in it like the Christmas pudding. The atom is electrically neutral because the number of negative charges is equal in magnitude with the number of positive charges.


Drawbacks of Thomson’s model of an atom:

It doesnot explain the stability of an atom. It does not explain about the nucleus of an atom.
