Not much. We could make some in the physics lab. But there is only the barest trace of this radioactive material anywhere on earth. Promethium has no stable isotopes, and the longest-lived isotope has a half-life of only about 17.7 years. This stuff disappears almost as rapidly as it is created in nature, and only a couple of elements produce it by radioactive decay. If there was none around, we wouldn't miss it much since there is so little to begin with. Use the link below for more information.
What else can I help you with?
How many valence electrons does promethium have?
Promethium has nine isotopes, their numbers ranging from 143 to 151. None of the isotopes are naturally occurring, yet some stars have minute amounts of promethium.
What would happen if acceleration didn't exist?
If acceleration didn't exist, objects would either be at rest or move at a constant speed in a straight line. There would be no change in velocity over time, and thus no ability to start, stop, or change direction. This would greatly impact motion and dynamics in the universe as we know it.
What would happen if physics does not exist?
Without physics, there would be no understanding of how the universe works, no laws governing the behavior of matter and energy, and no scientific framework to explain natural phenomena. Essentially, the fabric of reality as we know it would cease to function and the universe would be a chaotic and unpredictable place.
What would happen if an irresistible force met an immovable object?
This scenario is considered a paradox, as an irresistible force cannot exist alongside an immovable object in classical physics. It raises questions about the nature of the concept of an immovable object and an irresistible force.
What might happen if the strong force didn't exist and how would it impact the structure and stability of atomic nuclei?
If the strong force didn't exist, atomic nuclei would not be able to hold together, leading to the disintegration of atoms. This would result in the collapse of matter as we know it, causing instability and potentially catastrophic consequences for the universe.
What phase changes can happen to promethium?
Promethium can be melted and boiled.
Why promethium rare?
Although promethium exist in nature as traces it is practically an artificial element.
Where is promethium on the periodic table of elements?
Promethium exist in nature only in traces; it is supposed that the Earth crust contain less than 1 kg promethium.
Is promethium synthetic?
Promethium is a natural chemical element. But because exist in nature only in ultratraces it is artificially prepared.
What is promethium?
Promethium is an element of the periodic table, atomic number 61, chemical symbol Pm.
Is promethium a natural or man made?
Although promethium exist in traces in the Earth crust it is an artificial element.
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 would happen if these standards didn't exist?
We would not no what to do
What would happen if matter didn't exist?
nothing would happen because there would be nothing
What would happen if God didn't exist?
If god didn't exist then the hole world and all the planets and galaxy's would never happen
Is promethium malleable?
Yes. Promethium is a rare earth metal and is found in the periodic table in the Lanthanide section. Its symbol is Pm and it has the atomic number 61. It was predicted to exist, but could not be found in the earth's crust. Promethium has no stable isotopes, and what ones it has are relatively short-lived. It was first isolated from spent nuclear fuel, and later discovered in ores of uranium, but only in the most minute quantities.
If there was no planets what will happen?
This question would not exist!
