Which subatomic particle has a positive charge and a relative mass of 1?

• A. Neutron
• B. Positron
• C. Proton
• D. Electron

Answer: (C)

Verified step by step guidance

1. Recall the three main subatomic particles: protons, neutrons, and electrons.
2. Identify the charge of each particle: protons have a positive charge, neutrons are neutral (no charge), and electrons have a negative charge.
3. Consider the relative masses: protons and neutrons both have a relative mass close to 1, while electrons have a much smaller relative mass (approximately 1/1836).
4. Match the particle with a positive charge and a relative mass of 1, which corresponds to the proton.
5. Confirm that the proton is the subatomic particle with these properties, distinguishing it from the neutron (neutral charge) and electron (negative charge and much smaller mass).
