At the Web Elements site you can download a PDF periodic table (at least I
know you can print it so I assume you can download it) that has the
elements and their atomic masses.  You can copy the data from it.  I also
am pasting a script which will return a dictionary with the keys being the
atomic number...double check it.  The "string" at the beginning is just a
copy of the spreadsheet that I created for my chemistry classes.
