Describe how j. j. thomson's cathode-ray tube experiments led to his plum pudding model of the atom

Cathode-ray tube experiment; in which negatively charged particles were observed led to J.J Thomson's Plum Pudding model of the atom. Pudding is bread like food in which plum (fruit) is embedded or evenly distributed. Based on the structure of this Plum Pudding, J.J Thomson developed the first atomic model, in which an atom is seen as spherical cloud of positive charge in which negative charges are embedded.

Explanation:

J.J Thomson performed cathode-ray tube experiment by passing high voltage into low pressured gas tube, the beam of light produced were seen to be deflected towards the cathode (positive electrode), hence the name cathode ray tube (CRT). J.J Thomson concluded that this beam of light must contain negatively charged particle since opposite charges attract.

This cathode-ray tube experiments led to Thomson's Plum Pudding model of the atom. Pudding is bread like food in which plum (fruit) is embedded or evenly distributed. Based on the structure of this Plum Pudding, J.J Thomson developed the first atomic model, in which an atom is seen as spherical cloud of positive charge in which negative charges are embedded.

there is no change in the electric potential energy as it is in rest on both conditions.
