Neptunium was prepared for the first time by Edwin Mac Millan and Philipp Abelson in USA in 1940.
Neptunium is radioactive, so it's usage would be somewhere in that realm. It is most often found as a biproduct of nuclear reactors and plutonium manufacture.

The name of the chemical element neptunium is derived from the name pf the planet Neptune.And Neptune was the got of seas in the Roman mythology.
It can.
Neptunium is not in foods.
Neptunium is an artificial element.Amounts of natural neptunium are absolutely nonsignificant.
Neptunium is a solid metal.
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.
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.
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.
Neptunium is a radioactive metallic element, and as such, it does not have a distinct smell. It is not typically found in nature but is produced in laboratories for research purposes.
Assuming you mean man[made], no. Trace amounts of neptunium are found in uranium ores in Nature.
Neptunium was for the first time obtained by Edwin McMillan and Philip Abelson at Berkeley Radiation Laboratories in 1940.
Neptunium was prepared for the first time by Edwin Mac Millan and Philipp Abelson at Berkeley Laboratories, USA in 1940.
Neptunium exist in nature in: - uranium ores, in extremely traces concentrations - in areas of past nuclear weapons tests
Edwin McMillan and Philip Abelson obtained for the first time neptunium in 1940 at Berkeley Radiation Laboratories, USA.
