Question

Define Thomson's model of an atom, also its limitation

Answer 1

the various chemical reactions that occur around us and the parameters governing these reactions, we need an understanding of the elements and compounds taking part in these reactions. The early developments in science revealed that matter is made up of atoms which in turn are composed of elementary particles known as electrons, protons and neutrons. In order to have a better understanding about the transformations of matter from one form to the other, the scientists needed a defined structure for an atom and its interaction with other atoms.

Answer 2

Thomson proposed an atom similar to that of watermelon and Christmas pudding. he proposed that atom is a positively charged sphere in which electrons are embedded. atom as a whole is electrically neutral .
limitations ...
although thomson 's model explained the atom as electrically neutral the results of experiments carried out be other scientists could not be explained by this model .
