Term: neodymium (Nd)
Literally meaning: ?pertaining to new twin?
Origin:
????/neos(new)
+???????/didimos(=twin)
The element called ?neodymium? because it was isolated from material named ?didymium? and forms greenish-brown salts.
Coined/History
In 1882 Bohuslav Brauner announced that ?didymium? incorrectly was said by Carl Mosander to be a new element (1841). In 1885 Baron Carl Auer Welsbach (1858-1929) recognized that ?didymium? was consisted of two new elements: praseodimium and neodymium. Welsbach reacted ?didymium? to form greenish-brown praseodymium and pink neodymium salts.
Definition
The element neodymium is a lustrous silvery-yellow metal with atomic number 60 and atomic mass 144,2. It is used with iron and boron to create powerful permanent magnents(NIB) ans as crystal in lasers.
