About Praseodymium

Praseodymium is a soft light grey color metal which is quite soft and easily produces various chemical compounds. It has got its name after the Greek expression meaning green lookalike. It is not toxic and not essential for living organisms on our planet. It can be found as a part of minerals and chemical compounds on the Earth crust. The applications of this element include producing green color in glass or ceramics, producing electrodes and some kinds of lights, and in producing goggles, due to the reflective properties of praseodymium.
