You can plot average mass per nucleon in which case iron-56 is the heaviest atom per nucleon. However if you plot binding energy per nucleon, then nickel-62 has the highest binding energy per nucleon. For elements with stable isotopes I'd …
WebI think it is hyrdrogen-7 which is 4n decay, half life is 21x10^-23 seconds. You need to give a source for your claim, which clearly states that the hydrogen-7 isotope has the shortest half life. The old KAPL Chart of the Nucleides on the wall gives H7 at 9E-22, H6 at 3E-22, H4 at 1.4E-22, and H5 as 'very short'. WebThe longest-lived is 289 and it has a half-life of 2.6 seconds. Nuclear theory suggests that isotope 298, with 184 neutrons, should be much more stable but that has yet to be made. Despite several attempts to make element 114, it was only in 1998 that a team led by Yuri Oganessian and Vladimir Utyonkov at the Joint Institute for Nuclear Research (JINR) in …

A half-life of 0.89 ms was calculated: 294 Og decays into 290 Lv by alpha decay. Since there were only three nuclei, the half-life derived from observed lifetimes has a large uncertainty: 0.89 +1.07 −0.31 ms. 294 118 Og → 290 116 Lv + 4 2 He. The identification of the 294 Og nuclei was verified by separately … Ver mais Oganesson is a synthetic chemical element with the symbol Og and atomic number 118.
