The rays that have negative charge are ___________?
Correct answer: B. Cathode Rays
- A. Anode Rays
- B. Cathode Rays
- C. Canal Rays
- D. Gamma Rays
Explanation
Cathode rays are streams of electrons emitted from the cathode, so they carry negative charge. Canal or anode rays contain positive ions, while gamma rays are electromagnetic radiation and have no charge; students may confuse cathode rays with the positive anode rays because both occur in a discharge tube.

About Discovery of the Proton
The discovery of the proton follows the study of positive rays, also called canal rays, observed in discharge tubes and later identified as positively charged particles. The work of Goldstein and Rutherford is linked to the proton's charge, relative mass and role in the nuclear model, distinct from the discovery of the electron.
