praseodymium词源

praseodymium (n.)

rare metallic element, 1885, coined in Modern Latin by discoverer Carl Auer von Welsbach (1858-1929) from Greek prasios \"leek-green\" (from prason \"leek\") + didymos \"double,\" the name given to an earth in 1840, so called because it was a \"twin\" to lanthana. When didymia was further analyzed in the 1880s, it was found to have several components, one of which was characterized by green salts and named accordingly, with the elemental suffix -ium.
