2. Bonding
Atoms use their valence electrons to form chemical bonds with each other
Bonded atoms are called molecules

3. Types of Bonds Ionic Bond Covalent Bond Metallic Bond
Atoms DONATE electrons to each other
Covalent Bond
Atoms SHARE electrons with each other
Metallic Bond
Atoms “pool” their electrons

4. Ionic Bond

5. Covalent Bond

7. Metallic Bond

8. Which Bond is it?! Metal + Metal = Metallic Metal + Nonmetal = Ionic
Nonmetal + Nonmetal = Covalent

10. Drawing It Lewis Dot Diagrams Write the Atomic Symbol
Fill in valence e- as dots around the symbol
Pair “single” e- of different atoms- replace with a line (OCTET RULE)
