Based on the data Thomson collected in his experiments using cathode rays, the concept of atomic structure was modified. Which of the following statements about the atomic structure were validated by his cathode ray experiments? Drag the appropriate labels to their respective targets. View Available Hint(s) Reset Help Particles within the cathode rays have mass. An atom is divisible into smaller subatomic particles. Particles of the cathode rays are embedded in a diffuse cloud of positive charge. Particles of the cathode rays are fundamental to all matter. Validated by experiment Not validated by experiment
