Neutronium, also known as Neutrium, is a theoretical element composed mainly of neutrons. The symbol n was given as the symbol of the predicted radioactive element. The element was suggested by Andreas von Antropoff in 1926 (before the neutron was officially discovered).

Neutronium starsEdit

The word neutronium is used in literature to refer to material located in the center of a star. "element of atomic number zero" that he placed at the head of the periodic table. However, the meaning of the term has changed over time, and from the last half of the 20th century onward it has been also used to refer to extremely dense substances resembling the neutron-degenerate matter theorized to exist in the cores of neutron stars; hereinafter "degenerate neutronium" will refer to this. Science fiction and popular literature frequently use the term "neutronium" to refer to a highly dense phase of matter composed primarily of neutrons.

UncertaintyEdit

People debate on if neutronium actually exists inside stars. It could be neutron-degenerate matter, strange matter, or quark matter in stars.

Andreas von Antropoff suggested the element in 1926 and was originally placed above the noble gases.

It is now placed above and to the left of hydrogen.

If neutronium is to be discovered, the mentioned neutron clusters mononeutron, dineutron, trineutron, tetraneutron and pentaneutron would be considered isotopes of the element.
