Prospects for studying Fl and Mc chemistry

Nonmetalloid

As per the present article, the element is listed as a possible metalloid. Metalloids are elements which resemble metals in appearance, but chemically they are more like nonmetals. I here by define a new term, 'Nonmetalloid' which is just the opposite to 'Metalloid'. ie. a Nonmetalloid physically resembles a nonmetal but chemically resembles a metal. Anoop Manakkalath (talk) 10:09, 18 October 2019 (UTC)[reply]

Has any reliable source ever used this term? Wikipedia is not for things made up one day, so if unsourced, this cannot be added in the article. Sorry. ComplexRational (talk) 10:49, 18 October 2019 (UTC)[reply]

No. That's why I try to introduce a new term 'Nonmetalloid'. Anoop Manakkalath (talk) 06:38, 27 April 2022 (UTC)[reply]

If you're introducing it, then it definitely is original research and is inappropriate to include. Wikipedia is not the place for you to introduce stuff. ComplexRational (talk) 13:17, 27 April 2022 (UTC)[reply]

Zintl anions?

Are there any predictions so far about Flerovium's (in)ability to form anions?

It would be interesting to study the possibility of anion formation in elements like Nh, Fl, Mc, Lv and Ts, and in case that anions can be formed, whether they act similarly to their lighter homologues. Since most Zintl-type anions follow the classical octet rule, and since the "full" electron shell of Og is expected to be far less stable than that of its lighter homologues, anions of the elements 113-117 may not neccessarily follow this principle. On the other hand, Ts^- and Lv^2- are predicted to exist with their expected stability roughly following group trends. McH₃ and Mc₅^- (analogues of ammonia and pentazolide) seem to be possible as well. By contrast, FlH₄ is expected to be extremely unstable, much more so than PbH₄. But what about e.g. Fl^4- or Fl₄^4-? Do relativistic effects move the position of the Zintl line from element 113/114 to the right? Or is there a "new chemistry" appearing with anions like monomeric Nh^- adopting the electronic structure of Fl instead of Og?

(I have summed up information about predictions cited in other Wikipedia articles about these elements. I don't expect any satisfying answers to my questions in the second text block, as most of them will still be insufficiently studied to give really good answers. They are only there to explain my motive for asking about Zintl anions of Fl. I mean, anions of superheavy elements are no less interesting than cations, so I ask if there are any studies about Fl (and also Cp, Nh, Mc) occurring in negative oxidation states.) --2003:E0:7F07:54B5:B536:BD88:CD75:3D8E (talk) 15:46, 25 June 2021 (UTC)[reply]

Wikipedia is not a discussion forum. We also don't engage in speculation. –LaundryPizza03 (d c̄) 17:08, 25 June 2021 (UTC)[reply]

Why exactly is this unscientific speculation? It is just a summary of theoretical calculations which have been cited in various Wikipedia articles. Besides, Nh- is expected to be possible. See the article on Nihonium. --93.195.28.183 (talk) 15:07, 26 June 2021 (UTC)[reply]

We need an academic source abut this specific prediction. –LaundryPizza03 (d c̄) 17:21, 30 June 2021 (UTC)[reply]

Hg is probably the best guide we have for how Fl should behave. But extending it to clusters is still OR. Double sharp (talk) 01:20, 26 January 2023 (UTC)[reply]

Flerovium-290

A paper published in 2023 seems to disfavor an interpretation of an empirical result which attributes a 1999 decay chain to ²⁹⁰Fl:
