Lanthanum - 57La: historical information

  • Discoveror: Carl Gustaf Mosander
  • Place of discovery: Sweden
  • Date of discovery: 1839
  • Origin of name : from the Greek word "lanthanein" meaning "to lie hidden".

Carl Gustav Mosander recognized the element lanthanum in impure cerium nitrate in 1839. His extraction resulted in the oxide lanthana (La2O3). A number of other lanthanides (rare-earths) were later discovered by identification of the impurities in yttrium and cerium compounds.
