Praseodymium (Pr)
Semi-isolated in 1841, praseodymium was clearly identified as an element in 1885.
Praseodymium is soft, silvery, malleable, ductile, and develops a green oxide coating when exposed to air.
It occurs with other rare-earth elements in various minerals, primarily monazite and bastnasite.
The rare-earth oxides, including those of praseodymium, are some of the most refractory substances. Along with other rare-earth metals, it is used for carbon arcs and to add a clean yellow color to glass and enamel. Its presence in didymium glass helps provide the protective coloring in welders' goggles.
