Entry: Praseodymium - showing version 4
URI: https://terra-vocabulary.org/ncl/DataTerraRepositoryFairIncubator/motsClefs/c_b652b5c8
[Wikipedia] Praseodymium is a chemical element with the symbol Pr and atomic number 59. It is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air.
