- n. A radioactive rare-earth element prepared by fission of uranium or by neutron bombardment of neodymium, having 14 isotopes with mass numbers ranging from 141 to 154 and used as a source of beta rays. Atomic number 61; melting point 1,168°C; boiling point 2,460°C; valence 3. See Table at element.
- n. a metallic chemical element (symbol Pm) with an atomic number of 61.
- n. a soft silvery metallic element of the rare earth group having no stable isotope; was discovered in radioactive form as a fission product of uranium
- 1945. From the name of the Greek god Prometheus, who stole the fire from Mount Olympus and brought it down to mankind. (Wiktionary)
- From Prometheus. (American Heritage® Dictionary of the English Language, Fourth Edition)
“This uncertainty of just what Prometheus was responsible for is echoed in the uncertainty of who discovered the element promethium, number 61 in the periodic table.”
“It's live and it's all about promethium, element 61.”
“But my dim-witted, testosterone blind buddies convinced me to take her off pathâ€ to get the underbelly coated with a mono-layer of promethium-deuterium-phosphate, otherwise known as PDP.”
“A bomb made of promethium would never stop exploding, whatever that means, so I suppose a razor made of promethium would never dull.”
“For an issue in which chemical numbers are important it's odd that the razor company would be named after promethium, element 61, which is nasty, radioactive stuff.”
“So's part of the sea floor — for the promethium mining and lutigestoid mariculture projects.”
“Hanford does it another way ... they always seem to generate too much promethium ... ”
“Morrow and his PTO team have raised more than $50,000, which helped two major capital improvement projects; outfitting three classrooms with promethium board technology, and a new playground structure that is currently under construction.”
“The trio also gave its discovery an unsettling name, promethium.”
“Nothing the Ordo Malleus and a little promethium can't fix.”
