← ScienceWhich outcome occurs regarding the decay rate when an unstable isotope is chemically bound within a molecule?
A)Decay rate may slightly alter✓
B)Decay rate accelerates exponentially
C)Decay rate remains unchanged absolutely
D)Decay completely ceases indefinitely
💡 Explanation
The electron capture mechanism weakly influences the decay of certain isotopes when chemically bound, because the electron density near the nucleus changes subtly; therefore, the decay rate may change slightly, rather than remaining absolutely constant in all conditions.
