|| This is easily the most complete periodic chart this reviewer has ever
The wealth of material is amazing! This reviewer clicked on silicon and was
transported to a page that linked to key data, history, uses, geology, biology,
reactions of silicon, compounds, bond enthalpies, radii in compounds, lattice
energies, reduction potentials, electronic configurations, ionization energies,
electron affinities, electronegativities, effective nuclear charge, electron
binding energies, atom radii, valence shell radii, bulk properties, thermal
properties, thermodynamic properties, crystal structure, NMR, naturally
occurring isotopes, radioisotopes, and a compound index. Each link leads to
superbly presented data.
A click on silicon (IV) fluoride lead to a screen giving synonyms, physical
properties, synthesis (not available in this example), isotope pattern, supplier
and references to the primary literature!
Humor is nor forgotten as cartoons are liberally strewn through the web site.
|| The Kossel shell description of electron configurations is very much
NON-standard and is likely to raise more questions among students than it is
worth. It should be relegated to a place of less prominence.
