...durch wesentlich kleinere Kugeln angedeutet. "...denoted essentially by smaller spheres.". Smaller than what is not clear to me from the original. I'm tempted to read this as ...wesentlich durch kleine Kugeln angedeutet. or "...essentially denoted by small spheres", but that's not what's written.
try this: "denoted by the relative sizes of the spheres"
- "wesentlich kleiner" = "considerably smaller" (or, more colloquially, "quite a bit smaller"). -- pne (talk) 09:59, 3 September 2009 (UTC)
ball-and-stick model bonds are not math lines
The article as is describes this model style's representation of the bonds as "straight lines" and links that to the WP article on lines as mathematical entities. Are we not referring instead to a model's actual component of bonds which may, depending on implementation, be represented with cylinders? It seems the concept of a ball-and-stick model is more general than a purely abstract conception of it. That is, a physical ball-and-stick model may exist, and its bonds are not lines. — 18.104.22.168 00:49, 19 June 2007 (UTC)
There should be something about the colour codes used for different elements. This thread mentions American and IUPAC schemes: http://www.natscience.com/Uwe/Forum.aspx/chem/1605/Atom-color-codes --22.214.171.124 (talk) 18:14, 22 September 2011 (UTC)
- Aha, the American one is CPK coloring. Is there an article for the IUPAC coloring? -- 126.96.36.199 (talk) 18:42, 22 September 2011 (UTC)
I was thinking about replacing the last paragraph to:
- The Beevers Miniature Models company in Edinburgh (now operating as Miramodus website ) produces models using PMMA balls and stainless steel rods. In these models, the use of individually drilled balls with precise bond angles and bond lengths enabled large crystal structures to be accurately created in a light and rigid form. Figure 3 shows a unit cell of ruby in this style.
- The Spiring Enterprises company in Billingshurst (operating as Molymod website ) produces sets for students.
But I am wondering if this would fall under Wikipedia:Commercial links (spam), I would like the community opinion on this. so lets discuss. Also note that molymod does redirect to this page ). Also probably my changes would need another section heading.WillemienH (talk) 20:19, 29 October 2015 (UTC)
