Heavy Nuclei Are Unstable Because

question 20

Multiple Choice

Heavy nuclei are unstable because

• A) each nucleon is a separate particle that is not acted on by the nuclear force.
• B) there are not enough protons present relative to the number of neutrons for the electrical force to be strong enough.
• C) the nuclear force dominates the Coulomb repulsive force at distances less than 2 fm, but falls off rapidly at greater distances.
• D) nuclei are stable only when the number of neutrons equals the number of protons.
• E) nuclei are stable only when the number of protons exceeds the number of neutrons.
