Neptunium is a transuranic element, meaning that it has so many protons that it does not occur in nature. Most commonly Neptunium is a byproduct of nuclear reactions and attempts to create Plutonium (another transuranic element).
Neptunium was obtained for the first time by Edwin McMillan and Philip H. Abelson in 1940 at Berkeley Laboratories.

For example, from neptunium-239 is obtained plutonium-239.
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 was obtained for the first time by Edwin McMillan and Philip H. Abelson in 1940 at Berkeley Laboratories. The nuclear reactions are: 23892U + n-------23992U-------23993Np + e
