The nucleus of an atom is the location of which kinds of subatomic particles?

• A. Neutrons and electrons
• B. Electrons and protons
• C. Protons and neutrons
• D. Only electrons

Answer: (C)

Verified step by step guidance

1. Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
2. Understand that the nucleus is the dense central part of the atom where most of the mass is concentrated.
3. Recognize that protons and neutrons are located inside the nucleus, contributing to its mass and positive charge (due to protons).
4. Know that electrons are located outside the nucleus, in regions called electron clouds or orbitals.
5. Therefore, the nucleus contains protons and neutrons, while electrons are found outside the nucleus.
