In a graph of nuclear radius versus nucleon number, what does a plateau indicate?.
- A.A constant increase in nuclear radius
- B.A saturation point in nuclear size growth
- C.A decrease in nuclear density
- D.An error in data collection
Model answer
What a good answer should say
- A saturation point in nuclear size growth
Explanation
Why this works
The evidence of a plateau in the graph suggests that beyond a certain nucleon number, the increase in nuclear radius becomes minimal. This indicates that there may be limits to how much the nucleus can expand as more nucleons are added.
The implication is that nuclear forces may reach a balance, leading to the conclusion that nuclear size growth is not infinite.
