What isotope is used for radioactive dating

isotope is converted into another specific atom or isotope at a constant and known rate.

Most elements exist in different atomic forms that are identical in their chemical properties but differ in the number of neutral particles—i.e., neutrons—in the nucleus.

The results show that there is no known process that can alter the rate of radioactive decay.

By way of explanation it can be noted that since the cause of the process lies deep within the atomic nucleus, external forces such as extreme heat and pressure have no effect.

The particles given off during the decay process are part of a profound fundamental change in the nucleus.

To compensate for the loss of mass (and energy), the radioactive atom undergoes internal transformation and in most cases simply becomes an atom of a different chemical element.

Likewise, the conditions that must be met to make the calculated age precise and meaningful are in themselves simple:isochron methods that make use of the rubidium-strontium or samarium-neodymium decay schemes, a series of rocks or minerals are chosen that can be assumed to have the same age and identical abundances of their initial isotopic ratios.

The results are then tested for the internal consistency that can validate the assumptions.

The situation is analogous to the death rate among human populations insured by an insurance company.

In terms of the numbers of atoms present, it is as if apples changed spontaneously into oranges at a fixed and known rate.
