Neptunium is an artificial chemical element. It is found in burned nuclear fuels and in very low concentration in soils as a product of nuclear weapons tests.
But natural neptunium exist in infinitesimal amounts in uranium ores.

Where is neptunium found in nature?
Neptunium exist in nature in: - uranium ores, in extremely traces concentrations - in areas of past nuclear weapons tests
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.
What is an element with 95 protons?
That would be Americium (Am). No, I am not making this up. It is an element that cannot be found in nature due to its nuclear instability, and can only be created synthetically.
Is neptunium corrosive?
Neptunium is dangerous due to it's radioactivity- it is similar to Uranium or Plutonium. It is likely to be chemically poisonous, but the radiation effects outweigh the chemical hazards. Neptunium is rarely found in a pure state, and results from decay of other radioactive materials, such as Plutonium and Americium.
Does neptunium have a smell?
Neptunium has not a smell.
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.
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.
Where is neptunium found in nature?
Neptunium exist in nature in: - uranium ores, in extremely traces concentrations - in areas of past nuclear weapons tests
Is neptunium man?
Assuming you mean man[made], no. Trace amounts of neptunium are found in uranium ores in Nature.
Is zinc manmade or naturally occurring?
Both. Zinc can be found in nature and also can be manmade.
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 conmen is neptunium in Earth's crust?
Neptunium does not occur in nature.
Is lantern manmade or nature?
Manmade actually.
How abundant is neptunium?
Neptunium is an artificial chemical element; in the nature infinitesimal amounts of neptunium are possible in uranium ores.
Can neptunium be found in food?
Neptunium is not in foods.
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.
Is Barium manmade or natural?
It is a natural element but, because it is highly reactive, pure barium is not found in nature.
