Which elements have the most stable nuclei because they have the greatest binding energy per nucleon?

Question

Quizplus · Accepted Answer

Iron and nickel have the most stable nuclei because they have the greatest binding energy per nucleon, which means the amount of energy required to remove a nucleon from the nucleus is the highest for these elements. This is due to the nuclear forces being stronger in these elements, leading to a tightly bound and stable nucleus. Hydrogen and helium have relatively low binding energies, while krypton and barium have intermediate binding energies. Uranium and plutonium have high binding energies, but they also have more unstable isotopes due to their large atomic number and tendency to undergo radioactive decay.
