Correct answer: A. Nucleon
- A. Nucleon
- B. Meson
- C. Boson
- D. Quartz
Explanation
Protons and neutrons are collectively called nucleons because both are particles found in the atomic nucleus. The likely mistake is choosing meson, which is another type of subatomic particle but is not the general name for protons and neutrons.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
