Radioactive or radiometric dating
A new, more stable isotope, called the decay, or daughter product, takes its place.
The isotope doesn't actually deteriorate; it just changes into something else.
Other common isotopes used in radioactive dating are uranium, potassium, and iodine. We have over 200 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.
The half-life is so predictable that it is also referred to as an atomic clock.Each element is made up of atoms, and within each atom is a central particle called a nucleus.Within the nucleus, we find neutrons and protons; but for now, let's just focus on the neutrons.Absolute age is just a fancy way of saying definitive or specific age as opposed to the relative age, which only refers to how old or young a substance is in comparison to something else.To illustrate, let's use the isotope uranium-238, which has a half-life of 4.5 billion years.
