which information can be determined using half - life?\nage of material\ntype of particle released\npercentag…

Brief Explanations:

Half - life is used in radioactive decay calculations. It helps determine the age of a material through radiometric dating. It can also be used to find the number of radioactive particles left based on the decay formula. The type of particle released is determined by the type of radioactive decay (alpha, beta, gamma etc.) and not directly by half - life. The percentage of rock that has aged can be related to the amount of radioactive decay which is based on half - life.

Answer:

A. age of material D. number of radioactive particles left
