Description
The rare earth metals family is more formally known as the lanthanide series and that's because lanthanum kicks off that row of the table. Lanthanum is a relatively soft metal that when freshly cut looks has a medium gray luster similar to iron. However, in open air it slowly turns darker and darker over the course of a few days and then, eventually white (the color of its oxide). This process can be slowed down - but not prevented - by immersing the sample in mineral oil. Unfortunately, the only way to keep this metal in its unoxidized state permanently is to encapsulate it under argon or another noble gas.
