What type of dating is radioactive decay used for
Radioactive dating of rock samples determines the age of rocks from the time it was formed.Geologist determine the age of rocks using radioactive dating.Each of these modes of decay leads to the formation of a new nucleus with a more stable n:p ratio.Some substances undergo radioactive decay series, proceeding through multiple decays before ending in a stable isotope.Many of these substances have found useful applications in medical diagnosis and treatment, determining the age of archaeological and geological objects, and more.
Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.
An atomic nucleus consists of protons and neutrons, collectively called nucleons.
Although protons repel each other, the nucleus is held tightly together by a short-range, but very strong, force called the strong nuclear force.

A radioactive isotope is an isotope whose nucleus tends to release particles, radiant energy, or both; Radioactive dating is a technique for determining the age of material by measuring the amount of a particular radioactive isotope the material contain.
