PHONETICS

IDENTIFICATION

Samarium is a moderately hard silvery metal that readily oxidizes in air and usually has the oxidation state +3, has no significant biological role and is only slightly toxic.

ELEMENT BRIEF

1879 by Paul Emile Lecoq de Boisbaudran, France.

DISCOVERY

From the name of the mineral, Samarskite, in turn honouring Vasili Samarsky-Bykhovets.
