Rare Earth Elements - Purdue University Lanthanum (La) is a soft silvery white coloured metal that has the atomic number 57 in the periodic table It is a Lanthanide metal Lanthanum is classed as a rare earth metal much like Yttrium It was discovered by Carl Mosander in 1839 in the mineral cerite
Periodic Table of Elements: Los Alamos National Laboratory Lanthanum is silvery white, malleable, ductile, and soft enough to be cut with a knife It is one of the most reactive of the rare-earth metals It oxidizes rapidly when exposed to air Cold water attacks lanthanum slowly, while hot water attacks it much more rapidly
Lanthanide - Wikipedia The term derives from lanthanum, first discovered in 1838, at that time a so-called new rare-earth element "lying hidden" or "escaping notice" in a cerium mineral, [11] and it is an irony that lanthanum was later identified as the first in an entire series of chemically similar elements and gave its name to the whole series
