As per Thomson's Theory;
- An atom contains only protons and electrons (there are no neutrons).
- An atom contains a positively charged sphere with negatively charged electrons embedded in it .
- The negative and positive charges are equal in magnitude , hence overall atoms are electrically neutral .
