The curve of binding energy per nucleon as a function of a atomic mass number has a sharp peak for helium nucleus. This implies that helium
Text Solution
Verified by ExpertsThe correct answer is:
B
A sharp peak (high binding energy per nucleon) means the nucleus is tightly bound, so it is very stable. Helium-4 has one of the highest binding energies per nucleon after iron/nickel region, making it extremely stable and difficult to break apart.
So, helium is very stable.
