The answer is: the accepted model of the atom has changed.J.J. Thomson placed two oppositely charged electrical plates around the cathode-ray tubes. Made experiments with different metals as electrode materials and found that the properties of cathode rays remained constant, no matter what material the cathode. Tomson the conclusion that atoms are divisible and that the corpuscles of their building blocks (atoms are composed of smaller particles). J. J. Thomson discovered the electron in 1897. His "plum pudding" model (1904) suggested: the electrons embedded in the positive charge. With this model, he abandoned his earlier hypothesis (that the atom was composed of immaterial vortices).
