Isotopes as tracer in carbon dating

Keep in mind that during this process, not all of the mass is conserved.

The 'heavier' atom that is produced is actually lighter than the two individual pieces, which means that mass is lost.

Radioactive isotopes have a variety of applications.

With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artifact, the age of the rock and the artifact can be determined.Because mass and energy are tied together, when mass is lost, energy is lost, or emitted.In a fusion reaction, massive amounts of energy are emitted.One of the interesting applications of radioactive decay is the technique of radioactive dating.Radioactive dating allows the estimation of the age of any object which was alive once, using the natural radioactivity of .It is assumed that level of carbon-14 in the atmosphere is constant.
