# Radioactive dating techniques

As radioactive Parent atoms decay to stable daughter atoms (as uranium decays to lead) each disintegration results in one more atom of the daughter than was initially present and one less atom of the parent.The probability of a parent atom decaying in a fixed period of time is always the same for all atoms of that type regardless of temperature, pressure, or chemical conditions. The time required for one-half of any original number of parent atoms to decay is the half-life, which is related to the decay constant by a simple mathematical formula.Plotting an isochron is used to solve the age equation graphically and calculate the age of the sample and the original composition.Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.The radioactive parent elements used to date rocks and minerals are: Radiometric dating using the naturally-occurring radioactive elements is simple in concept even though technically complex.If we know the number of radioactive parent atoms present when a rock formed and the number present now, we can calculate the age of the rock using the decay constant.Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.

The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

First, it provides no evidence whatsoever to support their claim that the earth is very young.

The number of parent atoms originally present is simply the number present now plus the number of daughter atoms formed by the decay, both of which are quantities that can be measured.

Samples for dating are selected carefully to avoid those that are altered, contaminated, or disturbed by later heating or chemical events.

Catholic dating sites bring the benefit of a large list of potential partners, as opposed to the small number of people you might find on your own.
