       The Lanthanides consist of the elements in the f-block in Period 6 of 
       the Periodic Table. They are soft, silvery, bright metals that all 
       naturally occur except for Promethium. They are also highly reactive 
       and strong reducing agents. Rare earth elements which are useful for 
       their metallurgical properties in alloy form are composed of the 
       Lanthanide family plus Scandium and Yttrium. They also have high 
       melting points and boiling points.
