Isotopic labeling or isotopic labelling is a technique used to track the passage of an isotope an atom with a detectable variation in neutron count through a reaction , metabolic pathway , or cell. The reactant is 'labeled' by replacing specific atoms by their isotope. The reactant is then allowed to undergo the reaction. The position of the isotopes in the products is measured to determine the sequence the isotopic atom followed in the reaction or the cell's metabolic pathway. The nuclides used in isotopic labeling may be stable nuclides or radionuclides.

Many rocks and organisms contain radioactive isotopes, such as U and C These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay.

The rare-earth elements , also called the rare-earth metals or in context rare-earth oxides , or the lanthanides though yttrium and scandium are usually included as rare-earths are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. The ending "-ide" normally indicates a negative ion. However, owing to wide current usage, "lanthanide" is still allowed and is roughly analogous to rare earth element. In pure form, these metals tarnish slowly in air at room temperature, and react slowly with cold water to form hydroxides, liberating hydrogen.
