How do I color a border on individual cells? -- Jarogers2001 09:09, 24 January 2007 (PST)

STYLE="border:1px solid #FF7F3F" where #FF7F3F is the selected color.

I gave up trying to color code cell borders to show Goldschmidt classification and imported the article from wikipedia. Jarogers2001 14:42, 16 February 2007 (PST)


Is it appropriate to list 117 when it has yet to be successfully synthesized? What about the Superactinides if so? --Strangelv 05:56, 24 January 2007 (PST)

Your call. I would wait until they have been made. -- Jarogers2001 08:51, 24 January 2007 (PST)
I went ahead and commented it out. We'll probably be uncommenting it out again soon enough anyway. We really need to solve the not enough neutrons problem so we can get some of these to have useful half-lives. -- Strangelv 16:05, 24 January 2007 (PST)


I added a section to the Key for radioactivity. Don't know how you color coded the symbols so its just a placeholder. Jarogers2001 22:29, 24 January 2007 (PST)

You can probably calibrate it much better than I can. What I was thinking in terms of:
Tiny Radioactive Symbol Gray.PNG Technically radioative, but a very long lived isotope exists
Tiny Radioactive Symbol Lime.PNG No known isotope lasts as long as four or so hours
Tiny Radioactive Symbol.PNG Somewhere in between
I was thinking more along the lines of radiation hazard, but whatever floats your boat. I dont think I can calibrate it much -- Jarogers2001 04:10, 26 January 2007 (PST)
Mostly I wanted to acknowledge the instability of Bismuth without having people look at their bottles of Pepto-Bismol with Geiger counters. Maybe more than three gradations? -- Strangelv 04:39, 26 January 2007 (PST)
Perhaps it should be a scale of gamma activity as opposed to half lives? technically radioactive, radioactive (standard), dangerously radioactive?
