How do scientists use the halflife of radioactive isotopes to date rocks and fossils?

The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.


How would you describe the isotopes of hydrogen?

Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Protium is the most abundant and consists of one proton and one electron. Deuterium contains one proton, one neutron, and one electron. Tritium has one proton, two neutrons, and one electron.

What is halflife about?

Half-life is the time it takes for one half of the radioactive material to decay. It is logarithmic, so after two half-lives, one quarter remains - then one eighth - etc.

All radioactive nuclides of an element have the same half life?

No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
