|
Answer» model of atomJJ Thomson in 1904 proposed that :◆ An atom is a uniform SPHERE of positive electricity in which electrons are embedded.◆ The negative and positive charge are equal in magnitude. So the atom is electrically neutral.Thomson model is ALSO called watermelon model.Drawbacks of Thomson modelAlthough Thomson model was able to explain the overall neutrality of the atom, it FAILED to explain the result of Rutherford alpha ray scattering EXPERIMENT. It was therefore soon rejected. |
