Color table
[edit]I grabbed this from an old revision of the ball-and-stick model page. Does anyone think it belongs in the body of this article?
element | color |
---|---|
oxygen | red |
carbon | black |
nitrogen | blue |
hydrogen | white |
sulfur | yellow |
iodine | purple |
chlorine | green |
bromine | orange |
- I brought over the "CPK color" table from molecular model, which is a superset of the above. However the color of the patches are very rough guesses and need to fixed by referene to some standard source, such as those listed in the "External links". --Jorge Stolfi (talk) 16:33, 28 January 2010 (UTC)
Not a well-defined concept,many versions
[edit]The article currently fails to explain that "CPK colors" is a very loose term that is used by different softwares and kit makers to label very different color schemes. The Jmol webpage has a table showing the hex color values and the difference between its coloring and that of Rasmol (which itself has two versions). Both tables are extensions and modifications of the "true CPK" scheme, used by Corey et al in the early 1950s. We should give that too. --Jorge Stolfi (talk) 16:41, 28 January 2010 (UTC)
- I have added a longer table with the Jmol and Rasmol color assignments for all elements up to 112. The C column has only four entries (C,N,O,H) because I do not know which of the colors in the first table were original CP (or CPK) and which ones were later additions. Help would be appreciated. All the best, --Jorge Stolfi (talk) 00:27, 29 January 2010 (UTC)
Photos of original CP(K) models
[edit]Unfortunately the 1952 online paper by Corey and Pauling has only black-and-white photos of their models. Perhaps someone can upload color pictures of their original models? They must have survived in science museums, probably at Caltech. (Some colors may have faded, though.) All the best, --Jorge Stolfi (talk) 16:41, 28 January 2010 (UTC)
- I noticed a nice color picture in W. Gerhard Pohl's paper history of molecular models but it only shows C,N,O,H atoms. It looks like a museum display. --Jorge Stolfi (talk) 00:27, 29 January 2010 (UTC)
Jmol colours
[edit]Might be better presented as a periodic table (stopping at Mt, of course). Double sharp (talk) 03:24, 29 July 2016 (UTC)
Wikipedia colours
[edit]We apparently have our own colour scheme as well: Wikipedia:WikiProject Chemicals/Elements coloring scheme. As this is the only one that covers all 118 known elements it may merit a mention, as it explains what we use here. Double sharp (talk) 05:34, 29 July 2016 (UTC)

Colored periodic table svg is slightly outdated
[edit]I've noticed that the CKJR table is fine, but the periodic table svg with Jmol's colors (https://wiki.riteme.site/wiki/File:CPK-coloring-periodic-table.svg) is not - It has a few minor color errors compared to the source that the CKJR table uses (http://jmol.sourceforge.net/jscolors/) - Fluorine is light blue in the image while it's actually supposed to be light green, Silicon is supposed to be beige rather than grey, Sulfur is supposed to be a lighter yellow.

Elements beyond meitnerium?
[edit]The elements beyond meitnerium have no color. HAt 03:12, 17 August 2024 (UTC)
