검증된 단계별 안내1
Recall the basic structure of an atom, which consists of a nucleus at the center and electrons surrounding it in orbitals.
Understand that the nucleus contains subatomic particles that contribute most of the atom's mass.
Identify the subatomic particles: protons (positively charged), neutrons (neutral), and electrons (negatively charged).
Recognize that protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.
Conclude that the subatomic particles located in the center of the atom (the nucleus) are protons and neutrons.
