Which of the following particles has the highest value of mass?
Correct answer: D. Baryons
- A. Photons
- B. Leptons
- C. Mesons
- D. Baryons
Explanation
Baryons are also composite particles and include protons and neutrons. They consist of three quarks (or three antiquarks). Due to their greater number of constituent quarks, baryons are generally much more massive than leptons and mesons.

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.
