which experimental evidence indicates that electrons are the constituents of all atoms
Answers
Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
Answer:
Cathode ray experiment by J. J. Thomson.
Explanation:
J. J. Thomson carried out an experiment and discovered the presence of electrons in all atoms. He did this experiment in the year 1897. He took a cathode ray tube in which cathode rays from one end of the tube to the other end was passed under the influence of electric and magnetic field. It produces fluorosence.
In cathode ray tube, electrons are accelaerated and strike the other end of the tube. In this process, elecrons lose energy.
