Identify the three main subatomic particles that make up an atom. These are protons, neutrons, and electrons.
Understand the role of each subatomic particle: Protons are positively charged and found in the nucleus, neutrons are neutral and also located in the nucleus, and electrons are negatively charged and orbit the nucleus.
Recognize that photons are particles of light and do not make up the structure of an atom.
Note that quarks are fundamental particles that make up protons and neutrons, but they are not considered subatomic particles in the context of atomic structure.
Positrons are the antimatter counterparts of electrons and are not part of the typical atomic structure.
