A graph shows the relationship between nuclear radius and nucleon number for various isotopes. What does the trend in the graph indicate about the nuclear radius as the nucleon number increases?.
Model answer
What a good answer should say
- The graph indicates that the nuclear radius increases as the nucleon number increases.
- This suggests that larger nuclei have more nucleons, which leads to a greater radius due to the additional space required for the nucleons.
Explanation
Why this works
The evidence from the graph shows a positive correlation between nuclear radius and nucleon number. This indicates that as more nucleons are added to the nucleus, the overall size of the nucleus increases.
The implication is that the structure of the nucleus is dependent on the number of nucleons, leading to the conclusion that nuclear stability and properties can be influenced by the size of the nucleus.
