Radioactive datingis a clever use of naturally occurring radioactivity. Its most famous application iscarbon-14 dating. Carbon-14 has a half-life of 5730 years and is produced in a nuclear reaction induced when solar neutrinos strike14N in the atmosphere. Radioactive carbon has the same chemistr...
II. Half Life Half-life: is the time it takes for half of the radioactive atoms to decay into a decay product. Half-Life Continued Decay Product- Daughter product, the element produced by the decay of a radioactive isotope. By studying the amount of decay product left over from the radi...
We know radioactivity is a spontaneous phenomenon. It obeys the exponential law and the lifetime of an atom can range from zero to infinity (∞). Thus, it is possible to determine the mean-life of a radioactive element. The lifespan of radioactive atoms therefore ranges from 0 to infinity...

Discover radioactive decay and the half-life equation. Learn how to use a half-life graph to write the equation for an atom's half-life and...
The term half-life is appropriate due to the exponential and quantum nature of radioactive decay, which makes it impossible to predict exactly when a single atom of radioactive material will disintegrate. The half-life measurement instead relates to stat
Half-life measurements for both ground-state and isomeric transitions in proton radioactivity are systematized by using a semiempirical, one-parameter model based on tunneling through a potential barrier, where the centrifugal and overlapping effects are taken into account within the spherical nucleus ...

half-life(redirected from half-lifes)Also found in: Dictionary, Thesaurus, Medical, Financial. half-life half-life, measure of the average lifetime of a radioactive substance (see radioactivity) or an unstable subatomic particle. One half-life is the time required for one half of any given...
half-life (haf'līf), The period in which the radioactivity or number of atoms of a radioactive substance decreases by half; similarly applied to any substance, such as a drug in serum, whose quantity decreases exponentially with time. Compare:half-time. ...
