In the simplified model of subatomic particles, what type of electric charge does a proton have?

• A. No charge (neutral)
• B. Positive charge
• C. Variable charge depending on the atom
• D. Negative charge

Answer: (B)

Verified step by step guidance

1. Recall that subatomic particles include protons, neutrons, and electrons, each with distinct electric charges.
2. Understand that a proton is a particle found in the nucleus of an atom and carries an electric charge.
3. Remember that the electric charge of a proton is a fundamental property and does not vary between atoms.
4. Recognize that the proton's charge is positive, which balances the negative charge of electrons in an atom.
5. Conclude that the correct description of a proton's electric charge is a positive charge.
