← ScienceWhich mechanism governs isotopic age estimations via rubidium-strontium dating?
A)Beta decay to stable strontium✓
B)Alpha emission altering both isotopes
C)Electron capture forming daughter isotopes
D)Positron emission of potassium isotope
💡 Explanation
Beta decay of rubidium-87 to strontium-87 changes their ratio within a mineral because it's a constant radioactive decay mechanism with a very long half-life; therefore providing an accurate date, rather than alpha where ratio changes aren't fixed.
