Nucleus: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

The radius of a nucleus is proportional to the cube root of its mass number ($R \propto A^{1/3}$). The ratio $R_S / R_{He} = (32 / 4)^{1/3} = (8)^{1/3} = 2$. Therefore, the radius is larger by a factor of 2.
