have set forth to make known any and all references to the elements that
can be found in comic books.
Simply click on the desired element in the periodic chart and be whisked
to another page to view scans
of the actual comic book pages containing the reference. With each element
they explain the history, its
physical properties, and key data. This is an interesting resource to introduce
chemistry for someone who
loves comic books.

OPPT Chemical Fact Sheets
A collection of indexed factsheets provided by the OPPT on toxic chemicals.
For each chemical listed, there is a document with frequently asked questions
about the chemical and a summary document about the chemical, itself. These
summaries include specific chemical information such as the CAS registry
number, properties (boiling point, melting point, density, etc. and references),
common name synonyms, production and manufacturing information, use, trends,
environmental fate, health effects, environmental effects, EPA and other
group activity in regards to
the particular chemical, and finally fully cited references for preparation
of the summaries.
Whether you're preparing mercury fulminate or enriching Pu-239, you'll find
the Chemicool Periodic Table
a handier reference than that musty old handbook on the shelf. There's a
colorful image map and all the
things you'd expect from such a reference, such as atomic number and weight,
density, and transition
states. But, wait. There's more. You also get energy levels, electron
configurations, physical properties,
standard reactions, radius, thermal and electrical conductivity, relative
abundance, and estimated cost.
Dump your old links; impress your colleagues with Chemicool.
