Theoretical chemical element, which lacks protons and would occupy the "0" place in the periodic table of the chemical elements. Although its existence has not been proven, the name 'neutronium' is used for the mass released by neutron stars because of the overload of their core. The proposed symbol is Nu and we owe the name to the Estonian scientist Andreas von Antropoff who in 1926 assumed the existence of this atom composed only of neutrons. See neutron, proton.
NEUTRONIO As we said yesterday: 1 . In the scientific field, neutronium is the residual nucleus of a neutron star that has released its neutrons leaving a very dense mass. 2 . Before the discovery of the neutron the German chemist Andreas von Antropoff invented in 1926 the term neutronium, also called "element zero", to refer to a theoretical substance consisting only of neutrons, ? that is, a chemical element without protons, which would therefore occupy the atomic number zero in the periodic table of the elements.
