Hi!

 Announcement
- ------------

At

http://members.lycos.nl/jupp/linux/soft/ruby/Periodic.html

you can find Peridic.rb

Periodic.rb is a Ruby module that provides information about all
chemical elements as a single constant table named Periodic::Table.
The database is taken from Gperiodic that is released under GPL. The
character set used for the table is ISO 8859-1. Information that is
not available is encoded as nil.

Periodic::Table[0] provides descriptions of the table's columns
(listed on the page), whereas Periodic::Table[1] through
Periodic::Table[118] provide information about H (Hydrogen) through
Uuo (Ununoctium) the index being the element's atomic number.

 RAA question
- ------------

RAA seemingly has no Chemistry section. Periodic.rb is rather
chemistry-oriented (it e.g. has no information about radioactive
decay channels or isotopes but oxidation levels) so that it does not
nicely fit in the Physics section.

Still I would recommend *not* adding such a section but rather
renaming the Physics section into Physics/Chemistry or
Chemistry/Physics (because there are not only physics and chemistry
but also physical chemistry or chemical physics).

What do others people think about that?
