credit by exam that is accepted by over 1,500 colleges and universities. Currently known uses of Neptunium metal are limited to research purpose only. Comprehensive data on the chemical element Neptunium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Neptunium. It is used as precursor in production of plutonium, which in turn is used as fuel in thermal generators to provide electricity to spacecraft and has applications in military. Block let's go. It is used in nuclear fuel as well.Neptunium – 237 is used for detection of high energy neutrons. The role of the element in humans, animals and plants. By the following year, this element was being called neptunium. In 1938, Horia Hulubei and Yvette Cauchois claimed to have discovered element 93, but the claim was also criticised on the grounds that element 93 did not occur naturally. Pornographic, defamatory, libellous, scandalous, fraudulent, immoral, infringing or otherwise unlawful use of the Images is, of course, prohibited. It can exist in many oxidation states, from neptunium (II) to neptunium (VII). Between those planets sits Neptune, and the gap between the two elements leaves a space for their relatively unsung cousin, neptunium - element number 93 in the periodic table. Applications. Common chemical compounds are also provided for many elements.
