ATOMIC MODEL LINKS FOR INSTRUCTION
special thanks to B. Lotze of California for this contribution

Please note that the Thinkquest sites have been down throughout February 2003.

• http://jersey.uoregon.edu/vlab/elements/Elements.html
  Click on an element and view the either absorption or emission spectra

• http://library.thinkquest.org/16468/hist-c1.htm
  Thinkquest site on atomic spectra that has some good animations of how electrons get energy

• http://library.thinkquest.org/16468/lab/atom/atom.htm
  Add energy or high speed electrons to an atom and watch what happens!

• http://users.erols.com/merosen/electron.htm
  Links to lots of electron configuration sites

Electron Configuration Animation Online 
Posted on the ChemEd-L by Doris R. Kimbrough of the University of Colorado at Denver - An Electron Configuration animation from the Okalahoma State University.  When you click on the screen, electron arrows are added to the energy level orbital diagram,  the element's identification changes and the visual obeys Hund's Rule.

Emission and Absorption Spectra of Elements 1-99
Online java applet that provides the emission and absorption spectra of elements 1-99.

Atomic Emission
Move electrons to different energy levels and observe absorption and emission of photons.
Atomic Emission Applet for Java Plugin (required for operation)
