Definition of radioactive dating in chemistry
Carbon-14 dating is a revolutionary advancement in the study of the history of our planet.
It is, in fact, leading to the “reconstruction of the history of the world”.
An unstable nucleus spontaneously emits particles and energy in a process known as refers to the particles emitted.
When enough particles and energy have been emitted to create a new, stable nucleus (often the nucleus of an entirely different element), radioactivity ceases.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
A process for determining the age of an object by measuring the amount of a given radioactive material it contains.
If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.
Uranium 238, a very unstable element, goes through 18 stages of decay before becoming a stable isotope of lead, lead 206.
Some of the intermediate stages include the heavier elements thorium, radium, radon, and polonium.
