Elements database 20001107
This dictionary database was created by Jay F. Kominek
 (Feel free to send any comments, additions,
corrections, money to that address) It was compiled from a variety of
sources, and is in my opinion, a work of my own. (The only stuff that
was really copied verbatim was the atomic numbers and weights, please,
I'd like to see someone try and exert a copyright on the values of
atoms.)
So, I place this in the public domain, if it somehow breaks, you get to
keep both pieces. It'd be nice if you kept the fact that I compiled the
information in here, but is not needed.
Up to date copies can probably be found on the web at:
Texts of the superheavy elements are copied from the Wikipedia.
