Terbium is reasonably stable in air means it will last for a pretty long time in air. It is malleable,ductile, and soft enough to be cut with a knife, it is not a very hard material so I could probably brake it with my hands. It is a rare earth metal found in Cerite, gadolinite,and monazite, we just learned that all the Lanthanoids and actonoids are rare earth metals. The element itself was only isolated recently. It is hard to isolate the Terbium as a pure metal. media type="youtube" key="2Nwr9E2BBTo" height="344" width="425"
