Which of the following figures correctly represent the shape of curve of binding energy per nucleon as a function of mass number?
Solution:
Here are some observations on the binding energy per nucleon vs. mass number (A) curve.
• The curve starts low for lighter elements.
• Peaks around A = 56 indicating maximum stability.
• Decreases slowly heavier elements.
(The curve peaks around A = 56 and then decreases.)
