The following resources are available in
inorganic chemistry:
1. General Chemical Information
o
CambridgeSoft
maintains ChemFinder, a remarkably
efficient Internet search engine, which searches for information on specific
compounds by name, formula, CAS registry number, and molecular weight. Most of
the hits are related to toxic properties but the search engine turns up
information that most tools such as Yahoo miss.
2. General Survey
o
The 80th.
anniversary issue of C&ENews published on 8 September 2003 contains an
informative set of essays on the elements. The article, The Periodic Table of the
Elements, is now available at the ACS Web site. The ACS also maintains its
electronic periodic
table which has the desirable feature of providing plots of properties such
as electronegativity. This periodic table appears courtesy of W. H. Freeman
Inc., publisher of Chemistry in the Community and CADRE design.
