Those that did the decaying are called parent nuclei.

If you have a rock that contains radioactive isotopes, these will decay over time.

There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.

Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.

The method assumes that the production of Carbon-14 in the atmosphere from nitrogen is a process that is in equilibrium, and it is not. Sedimentary rocks normally cannot be dated with radiometric methods (there are a few exceptions) because they do not have crystals that were consolidated at the time the rock was formed.Rubidium-Strontium and Uranium-Lead also has problems of the same kind.Potassium, Rubidium and Uranium salts are highly soluble.This serves as strong evidence for the reliability of radiometric dating methods. These isotopes differ in the number of neutrons they have in their nuclei.Those isotopes that are not stable decay into daughter nuclei.
