Guida verificata passo dopo passo1
Recall that atoms are made up of three main subatomic particles: protons, neutrons, and electrons.
Understand the electric charge associated with each particle: electrons have a negative charge, neutrons have no charge (neutral), and protons have a positive charge.
Identify that the question asks for the subatomic particle with a positive electric charge.
Match the positive charge to the proton, since it is the only subatomic particle among the options with a positive charge.
Conclude that the proton is the correct answer because it carries a positive electric charge.
