Lanthanum is a chemical element with symbol La and atomic number 57. It is a softductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. It is the eponym of the lanthanideseries, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. Lanthanum compounds have numerous applications as catalysts, additives in glass, carbon arc lamps for studio lights and projectors, ignition elements in lightersand torches, electron cathodesscintillatorsGTAW electrodes, and other things.
