Proton is formed by the loss of electron from which atom/ion?
Correct answer: A. Hydrogen
- A. Hydrogen
- B. Helium
- C. Carbon
- D. Neon
Explanation
When a hydrogen atom loses its electron, it becomes a hydrogen ion, specifically a hydrogen cation (H+). The hydrogen cation consists of a single proton in its nucleus, as the electron, which carries a negative charge, has been removed. Therefore, the loss of an electron from a hydrogen atom results in the formation of a proton. Helium is a noble gas and already has a stable electron configuration with two electrons in its outer shell. It does not readily lose electrons to form ions. Therefore, the loss of an electron from helium does not result in the formation of a proton. Carbon is an element that typically forms covalent bonds by sharing electrons with other atoms. It does not readily lose electrons to form ions. Therefore, the loss of an electron from carbon does not result in the formation of a proton. Neon is also a noble gas and has a stable electron configuration with eight electrons in its outer shell. It does not readily lose electrons to form ions. Therefore, the loss of an electron from neon does not result in the formation of a proton.

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.
