Recall the basic structure of an atom, which consists of a nucleus and electrons orbiting around it.
Understand that the nucleus is the central part of the atom and contains subatomic particles responsible for most of the atom's mass.
Identify the subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus.
Recognize that photons are not subatomic particles that make up atoms; they are particles of light.
Conclude that the two subatomic particles making up the nucleus are protons and neutrons.
