Rare-earth element - Wikipedia

The rare-earth element concentrations are not typically affected by sea and river waters, as rare-earth elements are insoluble and thus have very low concentrations in these fluids. As a result, when a sediment is transported, rare-earth element concentrations are unaffected by the fluid and instead the rock retains the rare-earth element concentration from its source.

Rare Earth Properties - ThoughtCo

22/6/2018· The rare earth metals are found in group 3 of the periodic table, and the 6th (5d electronic configuration) and 7th (5f electronic configuration) periods. There are some arguments for starting the 3rd and 4th transition series with lutetium and lawrencium rather than lanthanum and actinium.

Origin of rare gases in the earth - NASA/ADS

1/3/1980· Although terrestrial rare gases have elemental abundances similar to those of meteorites (planetary-type rare gases), their Ne and Xe isotopic compositions are quite different which suggests that degassing of meteoritic materials alone cannot explain the atmospheric rare gases. The terrestrial rare gases must contain heavily fractionated rare gases captured by planetesimals during a

Ilya Obodovskiy, in Radiation, 201912.3 Luminescence of the Rare Gases Noble gases are purely atomic gases. And although the formation of noble gas molecules due to the dispersion interaction is possible (Section 1.5.4), the binding energy of such molecules, however, is very small and the thermal motion easily cuts this connection.
