Which of the following best describes the relative charge of a proton?

• A. +1
• B. +2
• C. -1
• D. 0

Answer: (A)

Verified step by step guidance

1. Recall that the proton is a subatomic particle found in the nucleus of an atom.
2. Understand that the proton carries a positive electric charge, which is fundamental to the structure of atoms.
3. Know that the magnitude of the proton's charge is defined as +1 elementary charge, which is the standard unit of electric charge.
4. Compare the given options to the known charge of a proton: +1, +2, -1, and 0.
5. Conclude that the correct description of the proton's relative charge is +1, as it carries one positive elementary charge.
