//__[|Neptunium (NP)] __// **__[|History] of Neptunium __**

Neptunium was founded by Edwin M. McMillan and P. H. Abelson at 1940 in USA in 1940 at Berkeley, California, USA, who bombarded uranium with neutrons produced from a cyclotron. They named it after the planet of Neptune. It was the first synthetic Transuranium (elements after uranium) element discovered. It’s mostly produced in a lab but can be found rarely in a uranium ore in nature. It is used for Neutron detection instruments.

 * __ Bohr model of Neptunium __**



This element has a small role outside labs. It has no main role to living things due to its high levels of radioactivity. Its obtained to be used as a nuclear reactor. The symbol used for Neptunium is a representation of Roman god Neptune’s trident.
