Samarium

Samarium (Sm)

Samarium is the 62nd element in the periodic table and has a symbol of Sm and atomic number of 62. It has an atomic weight of 150.36 and a mass number of 152. Samarium has sixty-two protons and ninety neutrons in its nucleus, and sixty-two electrons in six shells. It is located in group Lanthanides, period six and block f of the periodic table. Soft silvery metallic element, belongs to the lanthanoids. Seven natural isotopes, Sm-147 is the only radioisotope, and has a half-life of 2.5*10^11 years. Used for making special alloys needed in the production of nuclear reactors. Also used as a neutron absorber. Small quantities of samarium oxide is used in special optical glasses. The largest use of the element is its ferromagnetic alloy which produces permanent magnets that are five times stronger than magnets produced by any other material. Discovered by Francois Lecoq de Boisbaudran in 1879.

History

In 1853, Jean Charles Galissard de Marignac discovered samarium when he found lines in mineral spectra. Paul Émile Lecoq de Boisbaudran isolated a samarium salt in Paris in 1879 from the mineral samarskite and identified a new element in it via sharp optical absorption lines. The pure element was produced only in 1901 by Eugène-Anatole Demarçay. From samarskite, a mineral named after Russian mine official, Col. Samarski

DiscoverersPaul Émile Lecoq de Boisbaudran
Discovery LocationFrance
Discovery Year1879
Etymology (Name Origin)Named after the mineral samarskite.
Pronunciationseh-MER-i-em (English)
Samarium is considered to be moderately toxic
Samarium metal can be produced by reducing the oxide with lanthanum

Uses

Samarium's main use is in samarium-cobalt alloy magnets for headphones, small motors and pickups for some electric guitars. Radioactive samarium-153 is used to kill cancer cells in the treatment of lung cancer, prostate cancer, breast cancer and osteosarcoma. Samarium and its compounds are also used as catalyst and chemical reagent. It is used in the electronics and ceramics industries. It is easily magnetized and very difficult to demagnetize. This suggests important future applications in solid-state and superconductor technologies.

Sources

Found with other rare earths in monazite sand. The sand is often 50% rare earths by weight and 2.8% samarium.
