J.J Thomson gave the first model of an atom in which its model is compared with a water melon or Christmas pudding. The reddish part of water melon represents positive charge ( protons ) and seeds embedded in it reflect negative charge ( electrons) . The total amount of positive charge is equal to total amount of negative charge. An atom as a whole is electrically neutral.

Limitations:-

1. This model didn't get experimental support and hence discarded.

2. This model could not explain the stability of an atom as there is no boundary of separation between positive and negative charge
