← ScienceWhich outcome regarding iron-56 (⁵⁶Fe) arises because it minimizes system energy?
A)High nuclear binding energy per nucleon✓
B)Maximum rate of radioactive decay
C)Isotopic abundance becomes nearly zero
D)Increased susceptibility to neutron absorption
💡 Explanation
Greater binding energy stabilizes the nucleus; iron-56 possesses peak binding energy per nucleon due to the strong nuclear force overcoming proton repulsion. This yields nuclear stability, rather than increased decay or scarce abundance because other isotopes don't optimize nuclear binding at each nucleon.
