Match the items given in Column-I with those given in Column-II
| Column-I | Column-II |
|---|---|
| (A) Magic number | (I) Nuclear fission |
| (B) Liquid drop model of nucleus | (II) Q-value |
| (C) Actinides | (III) Radioactivity |
(d)Threshold energy (IV) Shell model of nucleus
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Magic numbers come from the shell model, the liquid-drop model explains fission, all actinides are radioactive, and threshold energy is tied to the Q-value. A-IV, B-I, C-III, D-II (a).
