Time to get Atom.

We start our Chemistry learning about the nature and history of the ‘atom’ and Atomic Theory.

We’ll start by watching NOVA: Hunting the Elements which covers much of the content of the next 2 units Atomic Structure, Periodic Table, and Atomic Bonding.

Next, we’ll take some quick notes on the History of Atomic Theory to get us acquainted with the atom.  Here are the Slides :

And here is our reading on the structure of the Atom.

This TED-Ed does a great job of reviewing the History of Atomic Theory:

Lastly, here’s a modern reconstruction of the famous gold foil experiment that proved that most of all matter is actually empty space!

 

Bonding Time! Lewis Dot Structures

Our Second Unit this semester is Chemical Bonds.

We started with a brief book assignment:  Qs from the ends of sections 1-2 and 1-3 on Ionic and Covalent Bonds.  I’ve included a PDF copy of the book chapter HERE, (remember, just 1-2 + 1-3).

We then covered some basics of bonding with some (not all) of these videos:

Then took notes and practiced creating Lewis Dot (electron dot) stuctures for the first time.  See the PDF of the notes linked here.
