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.
The bombardment of uranium is with neutrons not protons.Neptunium has many isotopes; for example 237Np has a half life of 2,14.106 years.237Np will be used by United States as nuclear weapon.Other possible applications: precursor for the preparation of plutonium isotopes Pu-236 and Pu-238, isotopic tracer, in neutrons detectors.
None. Although Mercury, Uranium and Plutonium might seem to be named after planets they were not. They were named after ancient deities.
U238 is a stable isotope of uranium - it doesn't undergo decay except at a very very slow rate unless hit with Neutrons - then it will decay to Neptunium

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 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 prepared for the first time by Edwin Mac Millan and Philipp Abelson in 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.
No, neptunium is a radioactive element that is not naturally found in the human body and is not known to have any biological functions. Ingesting or being exposed to neptunium can be harmful to human health due to its radioactive nature.
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.
