Answer : J. J. Thomson’s experiment disproved the theory that an atom is indivisible.
Explanation : Scientist J.J. Thomson did his experiment to prove the existence of electrons. He did the experiment using a cathode ray tube, in which a vacuum-sealed tube with a cathode and anode on one end was placed which created a beam of electrons that traveled towards the other end of the tube. This was the theory that proved that atoms consists of many subatomic particles namely electrons.
The choices can be found elsewhere and as follows:
<span>is divisible. is indivisible.
contains protons.
contains electrons.
I believe the correct answer is the second option. </span><span>J. J. Thomson’s experiment disproved the theory that an atom is indivisible. Hope this answers the question.</span>
