Isotope stability range comparisons[edit]

Note that the stability range of atomic mass values for both 50Sn and 54Xe is the same, but that the element 50Sn has 10 stable elements within that 13 element range, whereas 54Xe only has 9. When examined, this difference is noted to be due to the slightly increased relative stability of the lowest EO isotope EO50Sn114 relative to the isobar isotope OE49In114 such that 0.34% of the 50Sn isotopes are stable with this mass number. In the case of 54Xe, the stability of the isotope OE54Xe127 is such that it is reported to be spontaneously changing to EO53I127 with a half life of 36.4 days. Both of these observations indicate a stability tendency in favor of nuclides with a larger number of neutron constituency in this area, with the trend being the addition of two additional neutrons for each additional proton.WFPM (talk) 14:12, 17 April 2010 (UTC)This is much better understood by looking at a modified nuclide chart, which I happen to have, than by a description.WFPM (talk) 11:37, 1 November 2010 (UTC)

The stability trend line in the area of the elements from 44Rh to 57 La has the formula A = 3Z - 32 and runs through 54Xe 130. But 54Xe is one of the EE elements of this group that has a lot of stable isotopes (9) running from 54Xe 124 to 54Xe 136. And in common with 50Sn and 52Te, 54Xe has stable elements at the high A number end with an exceptional number of extra neutrons, with 54Xe having 28 more than the Z number. Since the correction of the incidence of excessive extra neutrons is by B- emission, which changes the trend line number by 2 units, it is suggested that the way for these high extra neutron isotopes should decay back to the trend line values would be for them to undergo "double beta" decay, resulting in a 4 unit correction in the trend line correction number (plus a 2 unit increase in the Z number) toward the stability trend line.WFPM (talk) 11:37, 1 November 2010 (UTC)

For a discussion of the relationship of the characteristics of the 9 stable isotopes of 54Xe (Xenon) with respect to that of the single (monisotopic) stable isotope of 53I (Iodine) OO53I127, see Talk:Isotopes of iodine.WFPM (talk) 04:23, 27 August 2011 (UTC) Also see Talk:Nuclear model

Why is Xenon-108 not on the table?[edit]

Why does the table begin at 110Xe instead of 108Xe? — Preceding unsigned comment added by Balgontork (talkcontribs) 13:37, 20 May 2013 (UTC)
