From the table of data, substance C will have the least of the original amount remaining after 30 days even though it started with the most. which is the best explanation for this answer?

D)Substance C goes through a significantly larger amount of half-lives compared to the other substances.

Explanation:

Half life refers to the time taken for a radioactive isotope to decay to half of the original amount of radioactive substance present initially.

The shorter the half life of a radioactive substance, the more the amount of half-lives the substance undergoes within the given time period. Substance A will undergo five half lives within 30 days. Substance B will undergo six half lives within 30 days while substance C will undergo ten half lives within 30 days.

Since Substance C undergoes the highest amount of half lives within 30 days, substance C will have the least of the original amount remaining after 30 days even though it started with the most.
