Consistant Periodic Table

    Im working on a periodic table in vb.net and I want to start adding in the information for the density, melting point and boiling point for the elements. The problem that Im having is I need to find a source that I know has only entered these values for a specific temp and pressure. I prefer the temperature to be 20 celsius for the density and the pressure to be 1 atmosphere. Im going to use kelvin and g/cm3.

    Does anyone know of a source that always shows what pressure/temp its values are based on or a source that says up front that it is all based on a certain pressure and temp unless other-wise noted?

    Unless otherwise noted, they are almost always at STP, but I'd be surprised if it wasn't noted. Just Google for periodic table and check the first dozen or so hits - it shouldn't take that long.

    How do you know what they use for the melting point and boiling point on that periodic table? Are you sure it's consistant, the stp thing only seem to appear with the density about every 10 elements are so.

    Unless otherwise noted, it will be STP. I'd bet money one it. They have a source listed though, so if you wanted to, you could check the book out of the library...
