Why are technetium neptunium and promethium considered natural elements even though they are not found on earth?
In the last years technetium, prometium, neptunium and plutonium was found in the nature but in extremely low concentrations.Because they are found in the universe. They have been observed in the spectrum of certain stars.
What is neptunium the element found in?
Neptunium is an artificial chemical element but neptunium can be found also in the nature as a result of decay processes in uranium ores, only in ultratraces.
What elements before neptunium are not found in nature?
All the elements before neptunium are found in the nature. Also neptunium can be found in the nature only in ultratraces resulting from nuclear weapons experiments or other experiments.
How much does a pound of neptunium cost?
Neptunium is not a commercial material.
Where was neptunium found?
Neptunium is an artificial chemical element. Neptunium can be found in the nature only in ultratraces resulting from nuclear weapons experiments, radioactive wastes from nuclear reactors or from other experiments. Neptunium is found also in extremely low concentrations in uranium ores.
How much does neptunium weigh?
The density of alpha neptunium is 20,45 g/cm3.
Is neptunium man?
Assuming you mean man[made], no. Trace amounts of neptunium are found in uranium ores in Nature.
How much would neptunium cost per gram if it was for sail?
Neptunium is not a commercial product.
Is neptunium naturally occurring on earth?
No, if any Neptunium or Plutonium were present on earth when it formed, both would have decayed to undetectable levels before the first life formed. Small amounts would have formed naturally in early natural fission reactors (Oklo) but they too would have decayed long ago.
