WebSo, you can use the radioactive elements to measure the age of rocks and minerals. Below is a list of some common elements. Their useful range is from about 1/10 their half-life (the time it takes for half of the radioactive element/isotope-- the parent, to convert into a non-radioactive element/isotope-- the daughter) to 10 times their half-life.
