Chemistry 2-8-18 Photoelectric Effect & Wave Problems

CHEMISTRY: Fun field trip today!! Good job coming up with examples of the photoelectric effect. What? There really aren’t tiny people living in boxes above the doors at Wal-mart? And I just thought of another one, what about those automatic flush toilets!

What did you think about the energy problems? Again, make sure you not only memorize formulas, but also 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!

Need practice? What about a help session?

Hon Chemistry 2-8-17 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! For now, it’s an lesson from last year, so fast forward past the syllabus part! πŸ˜‰

Have you begun by watching the videos on the Periodic Table of Videos site? Great place to gather information for the cLAB!

The videos that you must watch from the s-block are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/

The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!

The videos on from the f-Block that you need to watch are: neodymium, thorium, and
