Common NamePraseodymium
DescriptionPraseodymium, also known as 59pr or praseodimio, is a member of the class of compounds known as homogeneous lanthanide compounds. Homogeneous lanthanide compounds are inorganic compounds containing only metal atoms, with the largest atom being a lanthanide atom. Praseodymium can be found in dill, red beetroot, romaine lettuce, and spinach, which makes praseodymium a potential biomarker for the consumption of these food products. Praseodymium always occurs naturally together with the other rare-earth metals. It is the fourth most common rare-earth element, making up 9.1 parts per million of the Earth's crust, an abundance similar to that of boron. In 1841, Swedish chemist Carl Gustav Mosander extracted a rare-earth oxide residue he called didymium from a residue he called "lanthana", in turn separated from cerium salts. In 1885, the Austrian chemist Baron Carl Auer von Welsbach separated didymium into two elements that gave salts of different colours, which he named praseodymium and neodymium. The name praseodymium comes from the Greek prasinos (πράσινος), meaning "green", and didymos (δίδυμος), "twin".
