History of Tungsten. Tungsten like all the elements having a higher atomic number than iron (Z>26) cannot be formed by nuclear fusion processes in stars as is the case for those elements with a lower atomic number but originates only by neutron or proton absorption of already existing bigger nuclei.These capture processes with extremely high fluxes of neutrons and protons occur exclusively
