Neutronium (Nu) is an element.
History[edit | edit source]
Neutronium was proposed by scientist Andreas von Antroproff in 1926. He placed it above helium and gave it the symbol -.This would be changed to Nu. The neutron was later discovered in 1932. Neutronium is not considered by all as an element. If it is, there are many isotopes.
Isotopes[edit | edit source]
Neutronium has 4 major known isotopes:
Nu-0, which has no neutrons, and is stable
Nu-1, which has one neutron, and beta decays to Hydrogen-1 in 10 minutes
Nu-2, which has 2 neutrons, and emits a neutron to Neutronium-1 in an unknown amount of time
Nu-4, which has 4 neutrons, and emits 3 neutrons to Neutronium-1 or 2 neutrons to Neutronium-2 in 10^-21 seconds
Neutronium in neutron stars can act like high isotopes of neutronium. The mass of an atom of neutronium is 1.67×10^−27 kg and the mass of a neutron star goes from 1.1 to 2.14 SM. Therefore, if they are accepted, the "neutron star isotopes" go from Nu-1E57 to Nu-3E57.
Properties[edit | edit source]
Neutronium has no electronic structure (having no electrons) and as such cannot form bonds with other elements. This is why it is placed above helium. Neutronium is a gas at all temperatures and pressures, but becomes superfluid at extremely high pressures.
