Rare Earth Elements (Metals) - List - ThoughtCo

Classification of Rare Earths . The classification of the rare earth elements is as hotly disputed as the list of included metals. One common method of classification is by atomic weight. Low atomic weight elements are the light rare earth elements (LREEs). Elements with high atomic weight are the heavy rare earth elements (HREEs).
