Hon Chemistry 12-3-12 Photoelectric Efffect & Bohr Model of the Atom

HON CHEMISTRY: I figured anybody who ditched his honeymoon to finalize his work on atomic theory deserved to have his picture on our website. (And, by the way, great job making like electrons today – way to role play!)

Here’s a link to a great video clip that begins to show the connection between our lab on spectroscopy, the hydrogen emission spectrum, and how we can identify elements. And don’t forget the watch the other clips from this chapter! They’ll be very helpful as you study!! Spectrum of the Stars

Fun field trip today! Hey what about other applications of the photoelectric effect? Are there tiny people living in boxes above the doors at Wal-mart and Target? What about solar calculators? And hey – what about those automatic flush toilets!

Let me know if you need help with the problems? Don’t give up on the ones tonight! Here’s a hint, see if you can figure out a way to use the speed of light formula and the energy formula together. Bottom line, make sure you not only memorize formulas but be able to think through them to use them. Be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused – and that will help tons. Here’s the lecture from Monday
