← ScienceWhich outcome increases when Helium-4's nuclear binding energy decreases?
A)Alpha decay probability increases greatly✓
B)Nuclear stability gains noticeably strength
C)Fusion reaction rate remains constant
D)Atomic mass measurement error shrinks
💡 Explanation
Decreased binding energy weakens the strong nuclear force holding nucleons together; therefore, particles are more easily released via alpha decay because reduced stability and increased potential energy favor separation rather than remaining bound in the Helium-4 nucleus.
