Radioisotope Decay & Half-Lives: Rubidium-87 - Answers in …

Tīmeklis2024. gada 8. aug. · We can determine the amount of a radioactive isotope remaining after a given number half-lives by using the following expression: amount remaining = initial amount × (1 2)n. where n is the number of half-lives. This expression works even if the number of half-lives is not a whole number. Example 11.5.1: Fluorine-20. Tīmeklis2014. gada 3. sept. · Rubidium-87 is radioactive and decays to stable 87 Sr:-. 87 Rb → 87 Sr + β¯ + ⊽ + Q. A negative β-particle (β¯) and an anti-neutrino (⊽) are both emitted in this process. The decay energy ( Q) is shared as kinetic energy by these two particles. Fortunately this β-decay of 87 Rb is a single-step process. maxbilt trail tail led tail lights
