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.

the temperature of the gas, in k, not celsius.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
