in nuclear physics neutronium or element zero is a hypothetical element built solely from neutrons the word was coined by scientist andreas von antropoff in 1926 for the hypothetical element of atomic number zero with no protons in its nucleus that he placed at the head of the periodic table denoted by 1 history edit ernest rutherford proposed a hypothetical neutral particle in 1920 as combination of a proton and an electron with the atomic nucleus the proposed particle would be discovered by james chadwick in 1932 but the composition of this particle would ultimately found not to correspond to an electron plus a proton in the intervening years the particle came to be called a neutron a term invented in a 1926 paper by andreas von antropoff which also introduced the term neutronium the work 2 by von antropoff was on a new proposed form of the periodic table and included a conjectured element made up of neutrons with no protons or electrons which he placed as the chemical element of atomic number zero at the head of his new version of the periodic table 3 this neutronium was subsequently placed in the middle of several spiral representations of the periodic system for classifying the chemical elements such as those of charles janet 1928 edgar emerson 1944 4 5 and john d clark 1950 all of these authors believed neutronium would be a noble gas 1 chemistry edit neutronium is considered by some chemists to be a legitimate element with atoms called neutrons an element with no chemical properties whatsoever other chemists reject that point of view 3 polynuclear particles edit some modern work considers the combination of multiple neutrons 3 the dineutron containing two neutrons is not a stable bound particle but an extremely short lived resonance state produced by nuclear reactions in the decay of beryllium 16 evidence reported in 2012 for the resonance 6 7 was disputed 8 but new work reportedly clears up the issues 9 a trineutron state consisting of three neutrons has not been detected and is not expected to be bound 10 a tetraneutron is a hypothetical particle consisting of four bound neutrons reports of its existence have not been replicated 11 12 calculations indicate that the hypothetical pentaneutron state consisting of a cluster of five neutrons would not be bound 13 astrophysics edit neutronium is also the name of any substance composed solely of neutrons 3 the cores of neutron stars consist largely of neutrons and might be considered an example of neutronium 1 however neutron stars have a complex layered structure starting with neutron rich nuclei like 56 fe and progressing through a neutron fluid to a series of phases referred to as nuclear pasta 14 see also edit neutron degenerate matter references edit 1 2 3 stewart p j
