Hon Chemistry 2-15-19 Atomic Radii & Ionization Energy

HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii and ionization energy. You made some great connections today!

We’ve started a new part of the chapter! Don’t forget though that part of the first part of chapter is still important as you prepare for the test! Make sure you’ve making progress on watching the videos of elements from this chapter I mentioned earlier at periodicvideos.com. Very interesting(!), with tons of useful information!

The videos that you must watch from the s-block for the test 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 uranium. Go pop some popcorn and have some movie time!

Chemistry 2-15-19 Bohr Model & Quantum Model of the Atom

CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture from Friday. If you’re still having questions, you will not only want to watch this vodcast again, but also you might watch these video clips that we saw in class today – The Emission Spectrum of Hydrogen, and also this one Animated Quantum Mechanics.
