A collection of videos for Chemistry SL. Since Chemistry HL overlaps with Chemistry SL to a great degree, these videos can also be useful for Chemistry HL.
Not bad video about atomic emission spectrum of hydrogen. The discussion of the hydrogen emission spectrum starts around 2 minutes into the video. The whole video is not bad.
Great simulation that shows the VSEPR structures of molecules. It allows you to rotate the molecules to get a better view. Be careful with the bond angles of the models, but the bond angles of the real molecules are correct.
