This may be what <s>suffices</s> you are looking for : - [Periodic Table of Elements w. Selected Phase Transition Temperatures][1] ![enter image description here][2] This may get you started: - [MatDL - The Materials Digital Library Synopsis][3] - [NIST SRD][4] ( I would write them) - [Java Applet: Phase Transition Temperatures][5] (untested) It is a very good question, which I came across as well. You could just google-image search `phase diagram` + `ELEMENT` to copy and past the most appealing charts into a table in your editor of choice. If the intend is *personal use*, this might be the fastest route. **wolfram alpha** should allow you to look up the state of the element at a given pressure as follows: sodium phase at 0 bar Helium itself is a particularly interesting subject. I hope this helps for a start...
