Hydrogen as the atomic number 1 and promethium has the atomic number 61.
What is the physical state of promethium at room temperature?
The radioactive metal, Promethium, is a solid at room temperature and standard pressure. It becomes a liquid at 1040ºC and a gas or vapor at 3000ºC.
How much is promethium per pound?
Promethium is a highly radioactive element primarily created in the laboratory, though several of it's isotopes can exist in nature (it's longest-lived isotope has a half-life of only 17 years).
