Best Answer

A soft, ductile, silvery-white metal that tarnishes slowly when exposed to air. It is the first and the prototype of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the Periodic Table. It has no biological role in humans but is essential to some bacteria.
