Chemistry 4-3-12 Metallic Bonds

CHEMISTRY: Hey guys! Here’s the lecture on metallic bonding… make sure you can explain the properties of metals. Not just what metals do, remember, but why they do it (using the Electron Sea Model). We’ll play with one of the properties tomorrow!

Speaking of tomorrow, don’t forget about the 3-D Molecule Computer Lab that is due by the end of the day tomorrow. Be sure and save it to the server at school in your chemistry class folder. Follow the instructions on the 3-D Molecule Computer Lab instruction sheet. Good luck!

Whoops – I almost forgot to post the Water Wire Take Home Lab. Click here for a copy.

UPDATE: Here’s an updated vodcast on metallic bonds – hopefully the sound will work on this one.

Hon Chemistry 2-29-12 Metallic Bonds

HON CHEMISTRY: Wow! Who knew you guys had such “electric” personalities! Here’s the lecture on metallic bonding. Aren’t you glad there are no structures to draw! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.

We missed all you guys who weren’t here today! Because of the short period today, here is the change in schedule. The activity we were supposed to do today will be tomorrow (good news, you don’t have to write it up ahead of time in your lab book!), and then we’ll be back on schedule.

By the way, for those of you who’ve been absent, the 3-D Molecules Presentation is one that you can do at home, and then email to me. I’ll put it on the server for you if you aren’t here on Monday. You can find a copy of the 3-D Molecules Presentation here or under the project tab up top. There is one change on the compounds – the next to the last compound should be CH3CH2OH (the numbers are subscripts.) Holler if you have any questions!
