A full verion of the periodic table (For computer game) I am looking for a full set of data on every element on the periodic table. (and if possible those only speculated about)

When I say full I mean everything. Electron configurations, Valence electrons, melting point, Atomic mass, Isotopes and what they decay into and all the rest.

Is there such a database anywhere?
You can find all these information on Wolfram Alpha.  You can use the website directly to obtain these information, and you can call their API to directly fetch the data online from your own program.  Of course, you can also use Mathematica to write your program and query the database with WolframAlpha function.
