A table listing the 17 rare-earth elements, their atomic number and symbol, the etymology of their names, and their main usages (see also Applications of lanthanides) is provided here.

Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

Scientists have developed calibration techniques to adjust for these fluctuations.

While alive, all plants and animals take C14 into their bodies.

They are not especially rare, but they tend to occur together in nature and are difficult to separate from one another.

However, because of their geochemical properties, rare-earth elements are typically dispersed and not often found concentrated as rare-earth minerals in economically exploitable ore deposits.
