lanthanum
Soft silvery metal
Lanthanum is a soft, silvery metallic element, atomic number 57, the first of the lanthanide series of rare earth elements.
It has various industrial applications, particularly in catalysts for petroleum refining and in camera lenses.
The name comes from a Greek word meaning "to lie hidden," reflecting how difficult it was to isolate.
