No bell ringer
Quiz 4 - structural formulas, ball-and-stick models, space-filling models
Quiz 5 - memorized elements (may retake as many times as you need to get the score you want)
Bonds
Atoms bond until they have a full valence electron shell
This can be accomplished in 3 ways:
Taking electrons from another atom
Giving away electrons to another atom
Sharing electrons with another atom
Ionic bonds
Involves giving and taking of electrons
Always involves a "left side" element and a "right side" element
Bond happens because of charges (one atom becomes negative, the other becomes positive, and opposites attract)
