Which of the following isotopes is the most stable? A).⁶He,4.89 MeV/nucleon B).²⁰Ne,8.03 MeV/nucleon C).⁹⁴Zr,8.67 MeV/nucleon D).²⁴⁰Pu,7.26 MeV/nucleon

Question

Quizplus · Accepted Answer

The stability of an isotope is related to its binding energy per nucleon. The higher the binding energy per nucleon, the more stable the isotope. Among the given options, Zirconium (Zr) with 8.67 MeV/nucleon has the highest binding energy per nucleon, making it the most stable isotope listed.
