Final answer:
The strong nuclear force binds protons and neutrons in atomic nuclei and operates over very short distances, whereas the weak nuclear force is involved in radioactive decay and is weaker than the strong force.
Step-by-step explanation:
The statement that best describes the difference between strong nuclear forces and weak nuclear forces is: Weak nuclear forces are involved when certain types of atoms break down. Strong nuclear forces are responsible for holding atoms' nucleus together. The strong nuclear force is a very strong attractive force that acts only over short distances, about 10-15 meters, and is responsible for binding protons and neutrons together in atomic nuclei. The weak nuclear force, while also acting over very short distances, is much weaker and is involved in processes like radioactive decay and the production of neutrinos.
