Check out this great tutorial about the Quantum Atom!
(This is the one with the light gun and machine gun through the slits)
Also, here is a link to the machine that makes the crazy wave patterns, it is
known as a vibrating Chladni Plate

CHEMISTRY: Bohr Model ppt
Use the diagram on the second to last slide for part 1 of the worksheet. The "names" should be Lyman, Balmer and Paschen. The "Region of EM Spectrum" should be the span of kJ emitted by the group. For Paschen, look at the longest arrow above his name: the region his group spans is from -146 kJ to 0 kg. Use the arrows to find the span of Lyman and Balmer groups.
Use the diagram on the last slide to find the colors emitted by an excited hydrogen atom. Look at the four bars of color on the "Visible" part of the spectrum. The first bar is red, so write red under "color" column. Follow the arrow from the red bar to the maroon arrow which shows the movement of the electron from level 3 to level 2. In the "Transition" column write level 3 --> level 2. Do the same for the remaining three bars of color.
