Question

Select the correct answer. Which scientist performed the cathode ray experiment leading to the discovery of electrons? A. Dalton B. Rutherford C. Democritus D. Bohr E. Thomson

Answer 1

Hi,
The answer should be letter E, Thomson.

Answer 2

Thomson.

Step-by-step explanation:

J.J.Thomson performed an experiment called cathode ray experiment in which he used a sealed tube fitted with two electrodes.

When a high voltage was applied, the cathodic electrode emitted some particles which moved towards anode. These particles were negatively charged and discovered as electrons.

So he discovered electrons.
