Recall the three main subatomic particles found in an atom: protons, neutrons, and electrons.
Understand the electric charge associated with each particle: electrons carry a negative charge, neutrons have no charge (neutral), and protons carry a positive charge.
Identify that the question asks for the particle with a positive electric charge.
Match the positive charge to the proton, as it is the only subatomic particle among the options that carries a positive charge.
Conclude that the proton is the correct answer because it carries a positive electric charge.
