Column-IColumn-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).
