A Substance Is On Its Fifth Half-Life. Which Approximates The Percentages Of Radioactive And Stable Isotopes, Respectively? 96.9%; 3.1% 3.1%; 96.9% 12.5%; 87.5% 87.5%; 12.5%. In this first chart, we have a radioactive substance with a half life of 5 years. 【solved】### 3.1\%, 96.9\% explanation ## step1:
Radioactive Isotopes Half Life from ar.inspiredpencil.com
In this first chart, we have a radioactive substance with a half life of 5 years. The activity of a radioactive source was found. \[ \text{remaining isotope} = \left(\frac{1}{2}\right)^5 \times 100% = \frac{1}{32} \times 100% = 3.125% \] this means that approximately 3.1% of the original radioactive isotope remains.
\[ \Text{Remaining Isotope} = \Left(\Frac{1}{2}\Right)^5 \Times 100% = \Frac{1}{32} \Times 100% = 3.125% \] This Means That Approximately 3.1% Of The Original Radioactive Isotope Remains.
Converting this to a percentage, 3.1% is the remaining. The activity of a radioactive source was found. In this first chart, we have a radioactive substance with a half life of 5 years.

【solved】### 3.1\%, 96.9\% explanation ## step1: Which approximates the percentages of radioactive and stable isotopes, respectively? As you can see, the substance initially has 100% of its atoms, but after its first half life (5 years) only 50% of the.
The Activity Of A Radioactive Source Was Found To Be 1200 Bq.
