Yeah, I don't remember the details well enough, but the main point is correct. The trouble with adding them to the infobox is that without half-lives it would not say anything new – and likewise there is not really much to say in the body about it either. I guess I could add a sentence cited to the
517:
because it fits better in the prose there - along with other predictions, rather than in its previous location in the section about attempted nucleosynthesis (Pu + Fe) - which should give details about the specific experiments and only talk about decay properties if element 120 was observed, which
443:= 184 shell closure, which should have some effect. It is even almost as good (except for the lowered asymmetry) as the beautiful dream Fm+Ca. So we could seriously think about making isotopes from 120 all the way to 120, which would give us a road open to the heavy Og isotopes Og and Og.
317:
Fricke (the source) predicts 320 without a half-life, same for elements 119 and 121. The information for nuclear properties is annoyingly scarce, and I decided to take whatever scraps I could find even if they did not always come accompanied by details.

OK for me. Shouldn't they be added to the infobox (isotopes list), and be present in body text? BTW, the numbers mentioned are: E119: mn=315, E120: mn=320, E121: mn=320 (so different from what you wrote). E121 has source Amador, not Fricke.

projectiles are being considered as long-lived radioactive beams. This is even better than the Cm+Cr and Cf+Ti reactions that will be tried, as Pu+Fe gives the compound nucleus 120* that hits the

Currently, the infobox says mass number=320 for the most stable isotope. However, that one is not listed in the infobox, nor mentioned in the text. Ubn is in text, but not in infobox.
