Week 2 • Atomic Structure and Bonding
Overview:
Atomic Structure and Bonding is a huge topic and
covers several chapters in any book. Here is a
quick list of ideas that need to be taught. I have
inserted several of my favorite teaching ideas.
Through our discussions, I hope other participants
will share their favorite teaching ideas,
demonstrations, and labs for your resource list.
