WebInner transition metals are usually put at the bottom of the periodic table. These elements were sometimes called rare earth elements or rare earth metals due to their extremely low natural occurrence. They include elements 57-71 (known as lanthanides) and 89-103 (actinides). The lanthanides are very similar.
