प्रश्न
State the significance of binding energy per nucleon.
उत्तर
- It enables us to compare the relative strengths with which nucleolus are bound in a nucleus for various species, and thus their stability.
- Nuclei with greater EB/A ratios are more stable than nuclei with lower levels of this quantity.
