What evidence supports the idea of approximately constant nuclear density across different nuclei?.
- A.The mass of the nucleus increases with the number of nucleons
- B.The volume of the nucleus increases with the number of nucleons
- C.The ratio of mass to volume remains relatively constant
- D.The binding energy per nucleon varies significantly
Model answer
What a good answer should say
- The ratio of mass to volume remains relatively constant
Explanation
Why this works
The evidence shows that as the number of nucleons increases, the mass and volume of the nucleus increase in such a way that their ratio remains constant. This implies that nuclear density does not change significantly with different nuclei.
Therefore, we can conclude that nuclear density is approximately constant across various nuclei.
