God invented promethium, specifically in the detonation of various supernovas and during the big bang. Promethium, however, is unstable and radioactive, with short half-life, and all traces of it have long since vanished. (Except, theoretically, for the alpha decay of promethium-145, but that has not been observed in nature.)
Bohuslav Brauner, in 1902, suggested the existance of element 61, when he noted an apparent gap between neodymium and samarium. Henry Moseley, in 1914, confirmed the existence of that gap. At Ohio State University, in 1938, some nuclides were discovered that might have been promethium, but there was insufficient chemical analysis to confirm that. At Oak Ridge National Laboratory, in 1945, the first promethium was synthesized and "discovered", as a result of nuclear fission. The team that did this was composed of Jacob Marinsky, Lawrence Glendenin, and Charles Coryell.

What else can I help you with?
Is Promethium magetic?
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
What is the normal phase of promethium?
Promethium is typically a solid at room temperature, specifically a metal.
Is promethium flammable?
Yes, promethium is flammable. It can ignite spontaneously in air and react with oxygen to produce heat and flames. Special precautions are necessary when handling promethium to prevent accidental fires.
What is promethium phase at room temperature?
Promethium does not occur naturally on Earth and is primarily synthetic. At room temperature, promethium is expected to be a solid metal.
What is promethium odor?
Promethium is a radioactive element and does not have a characteristic odor on its own. Any odor associated with promethium would likely be from compounds or substances it is combined with in a laboratory setting.
What element was discovered first hydrogen or promethium?
Hydrogen was discovered first in 1766, while promethium was discovered much later in 1945.
When was promethium discovered?
It was first discovered by Jacob A. Marinsky, along with a few other scientists in 1944. But he did not make his claim of Promethium until 1946. The place Promethium was first discovered is still unknown to me...
How was promethium discovered?
Promethium was discovered in 1945-47 in burned uranium fuels as a fission product.
