Radioactive atoms decay, or lose energy and subatomic particles…

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.Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism.Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount. It decays to Nitrogen 14 and has a half life of 5,730 years.This is a way to measure the proportions of a daughter isotope and the parent radioisotope of some element trapped inside a rock since the time the rock formed.A radioisotope is a form of an element with an unstable nucleus.
