Welkom

Hallo Chem Sim 2001, hartelik welkom op die Afrikaanse Wikipedia! Dankie vir jou belangstelling in Wikipedia. Ons werk hier aan die ideaal van ’n gratis en vrylik beskikbare, vrylik bewerkbare, neutrale en volledige ensiklopedie. Die Afrikaanse Wikipedia bestaan al sedert Desember 2001 en bevat reeds 115 909 artikels. Vanaf die begin van die projek het die gebruikers ’n aantal riglyne en uitgangspunte vir artikelbewerking en onderlinge samewerking opgestel. Nuwelinge kan hieruit voordeel trek. Jy mag dit behulpsaam vind om van die skakels in hierdie raampie te volg en met die projek vertroud te raak voordat jy begin bydra. Indien jou vingers jeuk om te eksperimenteer, kan jy gerus ons Sandput besoek: dit is juis vir die rede daar. Uiteindelik wil ons dat al ons gebruikers vry voel om hulle gang te gaan, maar dit doen natuurlik geen kwaad om ’n bietjie houvas te kry voor 'n mens in die diep kant in spring nie! Besoek gerus ook ons Geselshoekie, ons gebruikers staan gereed om hand by te sit, of bloot net hand te skud. ___ Verifieerbaarheid Die eerste van Wikipedia se drie kernbeleide ___ Geselshoekie Die gewilde bymekaarkomplek ___ Geen oorspronklike navorsing Die tweede van Wikipedia se drie kernbeleide ___ Sandput Eksperimenteer na hartelus ___ Neutrale standpunt Die derde van Wikipedia se drie kernbeleide ___ Redigeringsinstruksies Hoe maak ek: teks wat skuinsgedruk is? ’n opskrif? tabelle? ___ Wat Wikipedia nie is nie Daar is ook ’n paar dinge wat ons nié hier doen nie ___ Beelde As jy beelde wil oplaai ___ Beleefdheid Ken jou maniere ___ Wenke vir die skryf van ’n goeie artikel Soms sê die naam alles Hierdie bladsy, wat nou op jou skerm staan, is trouens jou persoonlike besprekingsbladsy. Die plek waar ander Wikipediane jou in die toekoms kan kontak en jy hulle dan kan beantwoord. Elke gebruiker het so ’n bladsy. Jy kan dus ook boodskappe op ander gebruikers se besprekingsbladsye los. Sluit boodskappe en besprekings altyd af met ~~~~ of deur op die handtekeningknop in die wysigingsvenster te kliek: sodoende word jou boodskap onderteken met jou gebruikersnaam en die datum en tyd waarop die boodskap voltooi is. Kliek dan as laaste op "Stoor bladsy" om enige bewerkings te stoor.

Vandalism

Please refrain from vandalism. See: Wikipedia:Geselshoekie#Chem_Sim_2001 Jcwf (kontak) 19:14, 12 April 2024 (UTC)

@Jcwf: It's no vandalism, I'm a chemist and this 3D model is completely nonsense. The salt is depicted as a cation next to an anion, but this is not correct. The correct representation would be a crystal structure. The user who has uploaded this structure was already banned on Wikimedia Commons because he flooded the pages with chemically incorrect images. The respective 3D model was already nominated for deletion and will be removed in 7 days. Chem Sim 2001 (kontak) 07:48, 13 April 2024 (UTC)

@Oesjaar:, @Pynappel: You are not the only chemist in the world. I am a retired chemistry lecturer with a PhD in solid state chemistry and 30 odd publications in the open literature. Including crystal structures. Yes the image could be improved, that is true. No, it is not 'completely nonsense' as it correctly shows the ions this (ionic) compound consists of. And worse than that, what you are doing is clearly not an improvement. It would be if you were replacing it with an image of the crystal structure. But you are not doing that. Instead you are just imposing your negative POV on this wiki and on all others. I am going to ask for you to be banned.

@Jcwf: Okay, I don't care about being banned on af.wikipedia.org. Do what you have to do ... Chem Sim 2001 (kontak) 14:19, 13 April 2024 (UTC)

What is so "correct" about it? The fact that it was predicted by calculation? The fact that it only exists at low temperatures? The fact that the study does not take into account the exact positions of the ammonium ion? (Their orientation is probably random at -20°C but that may change at lower T) The fact that the compound is sold in solution form that contains the loose ions rather than in crystalline form? The fact that this image was simply stolen from the publication?

Or are facts simply not important to you when pushing your POV?

I'm getting tired of arguing with you again and again, but one last time: The structure by Hoa112008 is completely incorrect and useless. It depicts a salt as simply cation and anion drawn next to each other, without any details about space group, crystal structure, orientations in the crystal structure, cell lengths etc. There are other users on the Wikiproject Chemistry on Commons, who support my statement. Hoa112008 was banned long ago because he continued to upload factually incorrect 3D models. One good example is c:File:Sodium-fluoride-3D-balls-ionic.png. It just depicts one single sodium cation next to one single chlorine anion. That's totally non-sense, because a correct depiction would be c:File:Sodium-fluoride-3D-ionic.png.
