The 15 lanthanides (or lanthanoids), [a] along with scandium and yttrium, are usually included as rare earths Based on their atomic masses, rees are often classified as light rare earth elements (lree) or heavy rare earth elements (hree). Rare earth elements (ree) are becoming increasingly important in electronic devices used in the defense, alternative energy, and communications industries
Minable deposits of rees are found in only a few locations. Rare earth elements (ree) are a group of 17 metallic elements consisting of the 15 lanthanoids in the periodic table, in addition to yttrium and scandium We support the geospatial component of mineral resources program research and provide public access to research results and geospatial information
Rare earth elements (rees), which comprise of only 17 elements from the entire periodic table, play a critical role to our national security, energy independence, environmental future, and economic growth.
