    From the discharge tube experiment ,Goldstein discovered the proton .For this he used a porous cathode and observed that certain rays were traveling from anode to cathode in the opposite direction to cathode rays .These rays were named as anode rays. The smallest unit of the anode ray beam was named as proton .
