You will find the information you need here
http://www.webelements.com/webelements/elements/text/periodic-table/phys.html
there are lots of other similar sites.
I am curious to know why you are so interested in the densities of elements

I'm not really interested in the densities, it's just the most varying info I can find and I thought it was a good place to start.
also, Bored C, I don't really need to know about the unstable isotopes. I will eventually single out some of the information as "experts only" for safety reasons, but for now I just need the most common.
and with carbon what I meant by forms was the difference in graphite, charcoal, and diamond.

"I don't really need to know about the unstable isotopes."
Indeed not, but perhaps you might want to know about the 4 stable isotopes of sulphur. (2 of them are present in very small quantities so they don't make much difference to the mass.)

" The match thing was just a joke but I'm still licking coal just because I can. "
It's good to have a hobby.
The shapes in 3 dimensions of some proteins (including enzymes) are held together by "disulphide" bonds. Also, at least part of the toxic nature of the "heavy metals" lead, mercury etc is due to the fact that these metals produce relatively strong bonds to sulphides. If those sulphides are part of an important enzyme you are in trouble.
Hair is largely held together by disulphide bonds; these can be disrupted temporarily which is how permanent wave hairdos are created. This also explains why charred hair stinks.

I prefer to ignore the synthetically created elements like tritium (H-3) and the majority of the actinide series just to set limitations. only so many elements can actually be discovered.

NEWS-I am building clay ball-and-stick models for different compounds to be listed on the website. However, I will need to find different hosting as freewebs is SUPER SLOW and SUPER UNCOMPATABLE with safari, which is the only browser my friend has. I can't update from home.
