Which three fundamental subatomic particles make up atoms in the human body?

• A. Quarks, leptons, and photons
• B. Protons, neutrons, and electrons
• C. Neutrons, positrons, and electrons
• D. Protons, electrons, and neutrinos

Answer: (B)

Verified step by step guidance

1. Understand that atoms are composed of three main types of subatomic particles: protons, neutrons, and electrons.
2. Recall that protons and neutrons reside in the nucleus of the atom, while electrons orbit around the nucleus in electron clouds or shells.
3. Recognize that protons carry a positive charge, electrons carry a negative charge, and neutrons are electrically neutral.
4. Note that quarks and leptons are more fundamental particles that make up protons and neutrons, but they are not the subatomic particles typically referred to when describing atoms themselves.
5. Conclude that the three fundamental subatomic particles making up atoms in the human body are protons, neutrons, and electrons.
