charge on proton is
Correct answer: A. Positive
- A. Positive
- B. Negative
- C. Neutral
- D. None
Explanation
The charge on a proton is positive because it is a fundamental particle with a positive electric charge, and its presence, along with negatively charged electrons, allows atoms to maintain overall electrical neutrality. The subatomic particle that has a negative charge is the electron. The subatomic particle that is neutral is the neutron. Neutrons are found in the nucleus of an atom alongside protons. This is incorrect since option A is correct.

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.
