Thomson's model of an atom

After the discovery of electrona, Thomson suggested the model of an atom in the year 1899. According to this model:

• An atom may be regarded as a positively charged sphere consisting of protons.
• The negatively cbarged electrons may be regarded as embedded in this sphere (plum pudding model).
• The positive charge due to the presence of protons and negative charges due to the presence of electrons balance each other and an atom is electrically neutral.
