1. Bell Work:
Use your periodic table to identify the following compounds as an ionic or covalent bond.
SO2
MgBr2 HF
Covalent
Ionic
Covalent

2. Make the following table…
Ionic Bond Covalent Bond Metallic Bond
Electrons are transferred.
Electrons are shared.
Electrons “swim” from atom to atom.
Metals to Nonmetals
Nonmetals to Nonmetals
Metals to Metals
Strong bonds
Valence e- = 8
Strong bonds

4. Show what you know… Which element is most likely to gain electrons?
Sodium
Neon
Nitrogen

5. Show what you know… Which atom would become an ion with a 2+ charge?
Potassium
Magnesium
Oxygen

6. Show what you know…
Which statement BEST describes the reactivity of the elements nitrogen, oxygen, and fluorine?
The nonmetals decrease in reactivity from group 15 to group 17.
Oxygen is the most reactive of all the elements listed.
Fluorine is the most reactive of all the elements listed.

8. Ionic vs. Covalent vs. Metallic
LET’S PLAY!
Ionic vs. Covalent vs. Metallic
You will randomly walk around the room.
When you hear the teacher shout out a certain bond, find a partner.
Ionic = Back to Back (stuck like magnets)
Covalent = Arm to Arm (sharing)
Metallic = Face to Face (with arms swimming)
