Which of the following best describes the electric 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 the electric charge of subatomic particles is a fundamental property that determines how they interact electrically.
2. Identify the three main subatomic particles: protons, neutrons, and electrons.
3. Remember that protons carry a positive charge, electrons carry a negative charge, and neutrons are neutral (no charge).
4. Specifically, the charge of a proton is defined as +1 elementary charge, which is the basic unit of positive charge.
5. Therefore, the best description of the electric charge of a proton is Positive (+1).
