Which of the following statements best describes the nuclear radius?.
- A.It is directly proportional to the mass of the nucleus.
- B.It remains constant regardless of the nucleon number.
- C.It increases with the cube root of the nucleon number.
- D.It decreases with increasing atomic number.
Model answer
What a good answer should say
- It increases with the cube root of the nucleon number.
Explanation
Why this works
The nuclear radius increases with the cube root of the nucleon number, as described by the relationship R = R0 * A^(1/3). This means that as the number of nucleons increases, the size of the nucleus increases, but at a decreasing rate.
