Queries and listings (talk moved to this new subthread) 06:50, 28 July 2022 (UTC)Background. BTW, I have shifted in Scholia from allotropes to isotopes topic here. 04:59, 28 July 2022 (UTC)) talk (Egon WillighagenYeah, just tell me :) I think the SPARQL query was written when people started working on the allotropes. I may need to update it. So, let's use GitHub. -- 12:31, 27 July 2022 (UTC)) talk (DePiep can you tell me how to contact the Scholia creators? Github? I am missing some isotopes... and even with HL=1s, they don't disappear completely ;-) -Egon Willighagen(4) Conclusion: Looks like the Scholia query is incorrect, most likely by overflowing (without message). lists 4765 isotopes (3 for Og). This number is more like the NUMBASE number, but not checked for such completeness yet.6 Same query stripped down to more basic output lists 2995 isotopes (still zero for Og). There is no query-overflow warning.5 The same Scholia query made generic (=for all elements) .three. But Wikidata has [4], Scholia lists zero isotopes: (Q1307)oganesson (1) For 06:19, 28 July 2022 (UTC)) talk (DePiep. en:Template:Infobox element/symbol-to--overview-isotopesFYI, my laboratory is at 11:07, 1 August 2022 (UTC)) talk (DePiep lists 43 isotopes: no isomers (m), only ground states. Systematic? (WD has ca 1322 m-isotopes in the 4765 hits). -Scholia, Bi07:44, 2 August 2022 (UTC)) talk (DePiep: For these three reasons, I won't use the Scolaria queries any more for curating the ~5k isotopes. That is: Og: all isotopes missing; Bi-list m-isotopes missing (systematically though ;-)); Bi-214: same isotope repeated in the list. -Abandoning Scholia 18:45, 1 August 2022 (UTC)) talk (DePiep. -(Q18888228)bismuth-216 ; (Q18888217)bismuth-214 eg double lists & counts same isotope Scholia, Bi20:39, 28 July 2022 (UTC)) talk (ArthurPSmith? the ptable tool: Are you familiar with DePiep@20:48, 28 July 2022 (UTC)) talk (DePiepWow!
