What is the relationship between nuclear radius and nucleon number?.
- A.The nuclear radius increases with the cube root of the nucleon number.
- B.The nuclear radius decreases with the square root of the nucleon number.
- C.The nuclear radius is directly proportional to the nucleon number.
- D.The nuclear radius is independent of the nucleon number.
Model answer
What a good answer should say
- The nuclear radius increases with the cube root of the nucleon number.
Explanation
Why this works
The nuclear radius (R) can be approximated by the formula R = R0 * A^(1/3), where R0 is a constant and A is the nucleon number. This indicates that as the nucleon number increases, the nuclear radius increases with the cube root of A.
