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

• A. Neutral (0)
• B. Double positive (+2)
• C. Negative (-1)
• D. Positive (+1)

Answer: (D)

Verified step by step guidance

1. Recall that a proton is a subatomic particle found in the nucleus of an atom.
2. Understand that the charge of a proton is a fundamental property and is always positive.
3. Recognize that the magnitude of the proton's charge is equal to the elementary charge, which is +1 in atomic charge units.
4. Compare the given options: Neutral (0), Double positive (+2), Negative (-1), and Positive (+1).
5. Conclude that the correct description of a proton's charge is Positive (+1) because it carries a single positive elementary charge.
