Definition

Praseodymium is a chemical element with the symbol Pr and atomic number 59. It is a soft, silvery-white metal that is part of the lanthanide series. Praseodymium is named after the Greek word "prasinos," which means "green."

Praseodymium is a rare earth element, which means that it is not very abundant in the Earth's crust. However, it is still relatively common, and it is mined in many parts of the world.

Praseodymium is a versatile element with a variety of applications. It is used in a variety of magnets, including permanent magnets, electromagnets, and loudspeaker magnets. Praseodymium is also used in lasers, fireworks, coloured glass, and hydrogen fuel cells.

Praseodymium is a relatively safe element, but it can be toxic if ingested in large quantities. It can also cause skin irritation and eye damage.

Praseodymium is an important element with a variety of applications. It is likely to become even more important in the future as new technologies are developed.

Different forms of the word

Noun: a silvery-white, soft, ductile, and magnetic lanthanide element with the atomic symbol Pr and atomic number 59.

Adjective: relating to praseodymium.

Etymology

The word "praseodymium" comes from the Greek words "prasios" (leek-green) and "didymos" (twin). The element was named after its green salts, which were found to be chemically similar to those of didymium, a now-obsolete name for the lanthanide element neodymium.

The first recorded use of the word "praseodymium" in English was in 1885.
