Guida verificata passo dopo passo1
Recall the three main subatomic particles found in an atom: protons, neutrons, and electrons.
Understand the charge associated with each particle: protons have a positive charge (+), electrons have a negative charge (-), and neutrons have no charge (neutral).
Identify that photons are not subatomic particles with charge; they are particles of light and have no charge.
Match the particle with a positive charge to the correct option, which is the proton.
Conclude that the subatomic particle with a positive charge is the proton.
