Isotope percentages
It is the noted high percentage (68+percent) constituency of the lowest number (Z=58) stable isotope of 28Ni that results in the atomic weight of 28Ni (58.6934) to be less than the previous element 27Co (58.9331). This is because all of the stable isotopes of 27Co have 59 nucleons, whereas 68 percent of the 28Ni isotopes are stable with only 58 nucleons.WFPM (talk) 17:34, 16 August 2010 (UTC) This illustrates a peculiarity of the atoms of the even Z elements in that they are able to remain stable over an increased and wider range of accummulated extra neutrons (above the Z number) than can the atoms of the odd Z numbered elements. EE28Ni58 is also noted to be unusual due to the exceptional low number of "extra neutrons" (greater than Z number) in its nucleus (there are only 2) as compared with its adjacent elements, whereas the stable isotopes in its neighboring elements are noted to be OE27Co59, with 5 extra neutrons and OE29Cu63 with likewise 5 extra neutrons. This illustrates the lesser need of the 28Ni58 for extra neutrons as a stabilizing factor.WFPM (talk) 18:51, 4 October 2010 (UTC)
It is also noted that element 28Ni Nickel is 2 elements lower than 30Zn Zinc in the transition metal series. And therefor the 2 extra neutrons of EE28Ni58 may have been the interference factor in the accumulation process that kept the atom from acquiring the additional 2 deuterons needed to become EE30Zn60 via the deuteron accumulation process.WFPM (talk) 18:09, 31 October 2011 (UTC)
That the trend in favor of increasingly heavy atomic size elements was still in existence at this point is witnessed by the fact that in addition to the stable isotope OE29Cu63 (69%), 31% of the 29Cu atoms were also stable at OE29Cu65 with 7 extra neutrons.WFPM (talk) 03:49, 5 October 2010 (UTC)
