What does a graph of nuclear radius versus nucleon number typically show?.
- A.A linear relationship between radius and nucleon number
- B.A constant radius regardless of nucleon number
- C.An increase in radius with increasing nucleon number
- D.A decrease in radius with increasing nucleon number
Model answer
What a good answer should say
- An increase in radius with increasing nucleon number
Explanation
Why this works
The evidence shows that as the nucleon number increases, the nuclear radius also increases. This indicates that larger nuclei have more nucleons, which contributes to a greater radius.
The implication is that the structure of the nucleus is dependent on the number of nucleons, leading to the conclusion that nuclear size is related to its composition.
