Neptunium is a chemical element which has a chemical symbol Np. The atomic number of Neptunium is 93. As a radioactive actinide metal, it is the first transuranic element. It is positioned just after the uranium in the periodic table which is named after the planet Uranus, led to Neptunium being named after the planet Neptune, that is the next planet after Uranus.
An atom of neptunium has 93 electrons and 93 protons, of which seven are valence electrons. Neptunium is a silvery metal and it gets tarnished when it is exposed to air. It occurs in three allotropic forms and it usually shows five oxidation states, that ranges from +3 to +7. It is poisonous, radioactive, pyrophoric, and can be accumulated in bones, that is why the handling of neptunium dangerous.
Although there are many false claims of its discovery made over the years it was first synthesized by Philip H. Abelson and Edwin McMillan in 1940 at the Berkeley Radiation Laboratory. Since then, many neptunium has been and is still produced by neutron irradiation of uranium in nuclear reactors. The high majority is formed as a by-product in conventional nuclear power reactors.
There are no commercial uses of Neptunium at present but it is used as a precursor in the formation of plutonium-238 which is used in radioisotope thermal generators to provide spacecraft with the electricity. Today we are here to provide you with the information about the electron configuration of the Neptunium.
