Final answer:

J.J. Thomson's experiment revealed the existence of electrons in atoms, altering the understanding of the atom's structure.


Explanation:

J.J. Thomson's experiment with the cathode ray tube showed that atoms contain tiny charged particles known as electrons. This discovery challenged the previous belief that atoms were indivisible and led to the development of the plum pudding model of the atom, where electrons were thought to be embedded in a positively charged sphere.
