Radiometric dating

When a rock cools from the molten to the solid state, its radioactive isotopes are immobilized in mineral crystal lattices and then decay in place. Knowing the rate of decay of one nuclear species nuclide into another, scientists can, in…. The elements uranium and thorium gradually decay into lead, different isotopes of lead arising from the various isotopes of uranium and thorium; some isotopes of lead are, however, not produced by any radioactive decay process. When the…. The bombardment of planetary and satellite…. Atomic nuclei of a radioactive element decay spontaneously, producing other elements and isotopes until a stable species is formed. The life span of a single atom may have any value, but a statistical quantity, the half-life of a macroscopic sample, can be measured;….

Radiometric dating

The nitty gritty on radioisotopic dating Radioisotopic dating is a key tool for studying the timing of both Earth's and life's history. Radioactive decay Radioisotopic dating relies on the process of radioactive decay, in which the nuclei of radioactive atoms emit particles. This releases energy in the form of radiation and often transforms one element into another.

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms.
