Atomic Structure

The class did 2 experiments on spectroscopy. They viewed gas discharge tubes through spectroscopes to see the line spectrum that is produced. Hydrogen, helium, mercury, nitrogen, oxygen, and strontium were some elements that were viewed. The line spectra was reproduced on the lab sheet.
Another lab that was done in class was to produce cool blue light. Students mixed luminol, perborate and copper sulfate in a beaker of distilled water. When the copper sulfate was added, the chemical reaction started. With the lights out in the classroom, the colour in the beaker was a blue luminescent one. This was an example of chemiluminscence.
We also covered the historical aspect of the quantum theory-read some bio's of the scientists involved in developing this theory.
Also saw a neat simulation showing an electron absorbing a certain amount of energy (photon) and travelling to an outer orbit. When the electron fell back to a lower orbit it gave off the energy in the form of coloured light.
