1. complete the chart below by placing a dot and the percentage next to each dot for the 2-7 half-lives. hint: the dot and percentage for the zero half-life and the first half-life have been completed for you as an example. predicted radioactive decay of an isotope 100 90 s 80 co 70 60 aso 2 40 100 % 50% 20 10 3 5 6 number of half-lives

Explanation:

Percentage will get be divided by 2 for each half life.

If it is 100 initially, 50 % will be remaining in the next half life.

From the 50 %, 25 % will go to daughter isotope and another 25 % will be remaining in the parent isotope.

From 25 %, 12.5 % will be remaining.

From 12.5 %, 6.25 % will be remaining,

Likewise, till 7th half life, the percentage will keep reducing by half to the value of 0.78125.
