Answer: It showed that all atoms contain electrons.

Explanation:

J. J. Thomson's experiments inside a cathode ray tube in the presence of an electric field showed that all atoms contain tiny negatively charged subatomic particles "electrons". Also, Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Furthermore, Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny positively-charged nucleus. Then, Rutherford proposed the nuclear model of the atom based on these results.
