Question

Calculating Half-Lives A scientist is studying a radioactive element that has a half-life of 63 years. Choose the correct answers from the drop-down menus to complete each statement about the element It will take years for half of the sample to decay. In 189 years, of the sample will be left. Scientists can figure out how old a sample is by multiplying the by the length of the half- life.

Calculating Half-Lives A scientist is studying a radioactive element that has a half-life of 63 years. Choose the correct answers from the drop-down menus to complete each statement about the element. It will take 63 years for half of the sample to decay. In 189 years, 1/8th of the sample will be left. Scientists can figure out how old a sample is by multiplying the half-life by the length of time it has been decaying.
