I got mine from the Handbook of Chemistry and Physics.
Refer to section 10.
You should find one in your chemistry lab's library.
That's where I got the data copied in the doc attached (sorry, argon is not in there).

If you are only doing a couple calculations that you are not given those values, I would just look up the individual elements on www.wolframalpha.com.
