Mineral Species sorted by the element La Lanthanum (original) (raw)

Lanthanum (La) Element Properties

Atomic Mass 138.9055
Atomic Number 57
Name Origins From the Greek, lanthanein = "to lie hidden."
Year Discovered 1839
Discovery Credits Discovered by C. G. Mosander at Stockholm, Sweden.
Remarks Soft, silvery-white metal; rapidly tarnishes in air and burns easily. Reacts with water to give hydrogen gas. Used in optical glass and for flints. La2+ is used as a biological tracer for calcium Ca2+.Diagnostic tests: There are no simple diagnostic tests to identify lanthanum. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
