History & Etymology
Promethium was the last of the rare-earths family elements to be discovered.
Henry Moseley's study of X-ray spectra confirmed in 1913-14 that an element was missing at atomic #61. A search of minerals containing adjoining elements brought claims of discovery.
Isolation and identification of element #61 was finally made in 1945 (confirmed 1947) by Charles D. Coryell (1912-1971) and his associates Jacob (Jack) A. Marinsky (b. 1918) and Lawrence E. Glendenin (1918-?), together with Harold G. Richter. They worked for the Manhattan Project at Oak Ridge, Tennessee, where scientists had to create the fuel for an atomic bomb. They identified 14761 in the by-products uranium fission. Element #61 emitted beta rays with a 3.7-year half life. 14761 was confirmed by mass spectrograph. The most stable isotope currently known has a half-life of 25 years, too short to be in any of the minerals investigated in the 1920s.
Prometheus
In Greek mythology, Prometheus (Ancient Greek Προμηθεύς, 'forethought') is a Titan, the son of Iapetus and Themis, and brother to Atlas, Epimetheus and Menoetius. He was a champion of human-kind known for his wily intelligence, who stole fire from Zeus and gave it to mortals. Zeus then punished him for his crime by having him bound to a rock while a great eagle ate his liver every day only to have it grow back to be eaten again the next day. His myth has been treated by a number of ancient sources, in which Prometheus is credited with – or blamed for – playing a pivotal role in the early history of humankind
(note).
Grace Mary Coryell suggested the name Prometheum since Promethium does not exist except in fission products, it was named after Prometheus for the courage and pain needed to synthesize new elements. In 1949 the International Union of Chemistry adopted the spelling Promethium.
