Question

The nucleus having highest binding energy per nucleon is

• A. \( ^{16}O_8 \)
• B. \( ^{56}Fe_{26} \)
• C. \( ^{208}Pb_{82} \)
• D. \( ^{4}He_2 \)

Hint:

The nucleus with the highest binding energy per nucleon is iron-56, which is the most stable nucleus.

Answer 1

The Correct Option is B

The binding energy per nucleon is a measure of the stability of the nucleus. The higher the binding energy per nucleon, the more stable the nucleus is. \( ^{56}Fe_{26} \) has the highest binding energy per nucleon among all known elements. This makes it the most stable nucleus in terms of binding energy. Thus, the correct answer is \( \boxed{^{56}Fe_{26}} \).
