Understand the basic structure of an atom, which consists of three main subatomic particles: protons, neutrons, and electrons.
Recall the charges associated with each particle: protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
Identify that the question asks for the positively charged particle, so focus on the particle with a positive charge.
Recognize that the proton is the subatomic particle with a positive charge, distinguishing it from neutrons and electrons.
Note that the nucleus is the central part of the atom containing protons and neutrons, but it is not itself a particle, so the correct answer is proton.
