Subject: The Elements
For all of you with an interest in the physical sciences - especially
chemistry - here is the site to end all sites when it comes to the
properties of the elements:
http://www.shef.ac.uk/chemistry/web-elements/
Mark Winter of The University of Sheffield in England has come up with an
excellent resource for information on the elements.
The first page of his website displays the well known periodic table.
When you click on an element you are presented with an amazing list of
possibilities. Besides the usual data and description that one would
expect, you have an opportunity to find out things you may never have
wanted to know:
The element's history.
It's name in various languages.
It's atomic structure: electronic shell configuration (in a graphical form
new to me), atom radii, ionization enthalpies, electron affinity,
effective nuclear charges, electron binding energies, valence shell
radii, NMR , naturally occurring isotopes as well as radioactive isotopes.
It's other properties: it's crystal structure (in interactive 3D!), bulk
properties thermodynamic properties, mass absorption coefficients.
Its compounds: The types formed, bond enthalpies, electronegativities,
compounds radii, lattice energies, reduction potentials
It's occurrence in our everyday lives
Actually, there may be more than the above depending on the element.
In addition, there are innumerable links to other sites and references.
Check it out.
Cheers.
