In the simplified model of subatomic particles, what is the electric charge of a proton?

• A. $-1$ (negative)
• B. $+2$ (positive)
• C. $+1$ (positive)
• D. $0$ (neutral)

Answer: (C)

Verified step by step guidance

1. Recall that subatomic particles include protons, neutrons, and electrons, each with characteristic electric charges.
2. Understand that the proton is a positively charged particle found in the nucleus of an atom.
3. Remember the standard charge values: electrons have a charge of -1, protons have a charge of +1, and neutrons have no charge (0).
4. Identify that the question asks specifically for the electric charge of a proton, which is known to be positive.
5. Conclude that the electric charge of a proton is +1 in the simplified model of subatomic particles.
