Basic Stuff about Atoms

Review Worksheet - The first worksheet handed out -- questions from the textbook, chapter 18, sections 1 & 2. Find the answers. (This may be easier after you watch the videos).

4  videos to watch - take notes on any new vocabulary words - like isotopes, valence electrons, atomic mass number, atomic number.  They are each 6-15 minutes long, and not exactly entertaining, but plow though, or take breaks. Listen more than note-take, just write down highlights, especially vocabulary.  (The more notes you take, the less you have to go back and re-learn.)

1. Atomic Structure meets the Periodic Table

2. Atomic Number, Mass Number and Net Charge

3. What is an Isotope?

4. Valence electrons and the Periodic Table 

Now that you have watched these four videos, and using the periodic table that I handed out in class, see if you can figure out at least some of the worksheet/chart that I handed out.  Some of you will find this kinda fun, and maybe some will think it is confusing to start, but give it a shot.  It's a puzzle.
