Question

Name the scientist and the experiment that led to the discovery of proton.

Answer 1

• E. Goldstein was the scientist who discovered protons in the cathode ray discharge tube experiment.
• During this experiment, he discovered the presence of new radiations known as canal or anode rays.
• Anode rays consist of positively charged particles and were seen moving from the anode towards the cathode in a specially designed discharge tube.
• These positively charged particles were named protons.

In this way, the proton was discovered.
