For example, if there is just one radioactive atom, and its half-life is one second, there will not be "half of an atom" left after one second.Instead, the half-life is defined in terms of probability: "Half-life is the time required for exactly half of the entities to decay on average".The carbon-14 undergoes radioactive decay once the plant or animal dies, and measuring the amount of carbon-14 in a sample conveys information about when the plant or animal died.Learn about different types of radiometric dating, such as carbon dating.
