Using half-life, you can determine the following information:
1. **Age of Material**: Half-life can be used in radiometric dating to estimate the age of an object, such as fossils or rocks, by measuring the remaining quantity of a radioactive isotope and comparing it to its known half-life.
2. **Number of Radioactive Particles Left**: By knowing the half-life of a radioactive substance and the initial quantity, you can calculate the remaining amount of radioactive particles after a certain number of half-lives.
The other two options listed (type of particle released and percentage of rock that has aged) are not directly determined by half-life. The type of particle released is related to the specifics of the radioactive decay process and does not depend on half-life, while the percentage of rock that has aged would require additional contextual information beyond just half-life measurements.
