HON CHEMISTRY – So why is molecular geometry important? I mean why is knowing the correct shape of molecules? Here’s the beginning of the answer! Great job on drawing dipoles. We’ll continue our discussion on intermolecular forces tomorrow.

Chemistry p-Block Elements
CHEMISTRY: Wow! There’s a ton of interesting and important stuff to know about the p block elements! To make things a bit easier for you, I’ve posted a vodcast that has all the notes on the p block in one place. Don’t forget to pay close attention to properties (physical & chemical), occurrence, and uses. (BTW – you’ll find vodcasts for the others block posted now as well!!)
As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself: the nitrogen cycle, arsenic poisoning – why it’s called inheritance powder, the symptoms, and the details of the Marsh test.
The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
Have you got the other questions from the d block elements researched and answered already? – The role of transition metals in gemstones (know colors and elements), the role of transition metals in alloys (know names, elements and uses), where the phrase “mad as a hatter” comes from, and the symptoms of mercury poisoning and why you should be careful if you eat a lot of fish! Check out the Chapter 5 Stuff to Know Sheet sheet for more.

Chemistry f-Block Elements
CHEMISTRY – Hey guys, isn’t this the coolest rock? The photographer found in the desert while he was walking his dog, and when he got home he put it under UV light and it fluoresced this green color. That’s because it contains small amounts of uranium. Cool, huh!
Here’s the lecture from today on the f-Block. The videos on periodicvideos.com from the f-Block that you need to watch are slightly different from the elements that I gave you take notes on (but you may want to watch those too!): neodymium, thorium, and uranium.

Chemistry d-Block Elements
CHEMISTRY: Just a deviant little group of elements, aren’t they? Did you find some interesting info when you researched these elements? Here is an old vodcast of the notes I gave one year on the d block elements – the transition metals. If you are unsure of your own notes, this vodcast might help!
Don’t forget that there are a couple of things from this block that I want you to research for yourself: the role of transition metals in gemstones (know colors and elements) and the role of transition metals in alloys (know names, elements and uses). Then I also want you to be able to tell me where the phrase “mad as a hatter” comes from and (here’s a hint!) what the symptoms of mercury poisoning are. Also, Make sure you practice writing electron configuration and using it to find period, block, group, and type of element!
Have you been watching the videos on 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!
