winpenpack.com, a site hosting free portable applications offers Periodic Table 3.8.5 :

QuoteThe application contains all the elements of the Periodic Table along with images of the elements in their natural state, as well as lots of other information and interactive displays. The periodic table now comes in three versions. They all contain the same amount of information. Standard, Mini and Zip. The last one is the best for a flash drive using. Standard and Mini are different only in their max graphic resolution. The Zip one needs only to be unzippep in a foilder you like for a portable usage.
nice
i saw a java applet someplace that had all the spectra - can't find it, now :'(
Don't know if this works, but here's the direct link from my DM

here is that applet i was talking about
you can click on each element to see the spectra
you can select absorptive or emissive modes

i thought it was pretty cool :P
Thanks :U
At least, I can see on my desktop.
O I C so Y(39) is emiting a light.
each element absorbs a specific set of colors called "spectra"
this is how we identify what other stars are made of, etc
even though the spectra may be red or blue shifted due to changing position, we can identify the element(s)
Look what I found

Just in case mars lot of silica, we can turn it into oxygen, but will take a lot of energy. Si had 4 hand, and it lots worse than carbon, very solid. But about 10000 C degree everything will breaking apart. As long as mars not cold enough.
Dave where are you?? Just ignore the other member opinions about beeing retired, I need you :cheekygreen:
mars is surprisingly cold
as for getting to 10,000F, it would be cheaper to carry the oxygen there - lol

We can send a few nuclears we got from here did not we? The overhead cost is bigger than we anticipated, it is cheaper if we just attack another country. :cheekygreen:
