Verified step by step guidance1
Understand that the nucleus of an atom is the central part of the atom where most of its mass is concentrated.
Recall that the nucleus is composed of two types of subatomic particles: protons and neutrons.
Protons are positively charged particles, while neutrons have no charge (they are neutral).
Electrons are negatively charged particles, but they are not part of the nucleus; they orbit around the nucleus in electron clouds.
Therefore, the particles that make up the nucleus of an atom are protons and neutrons.
