- [Properties]
-
- Yttrium is a silvery, ductile metal. Powdered samples burn easily, and
- thin turnings of the metal from metalworking lathes have been known to
- ignite spontaneously.
- Yttrium is a Group-IIIB element. Among other things, this means it is a
- fairly active and moderately lightweight rare-earth metal. Some chemists
- still argue that scandium (Sc) is not a rare-earth element and that
- yttrium is the first on the table and the lightest of all the rare earths.
