Rare Earth Elements

These elements got their name from the fact that chemists first isolated them in their oxide forms. These oxides somewhat resemble calcium, magnesium and aluminum oxides, sometimes called common earths. The rare earths all have three valence electrons. Because of this they all have similar properties.
