Unit Two: Molecular and Ionic Compound Structure and Properties (Bonding)

Goals of Unit 2 Include:

• Determining the type of chemical bond

• Describing the structure of ionic solids, metals, and alloys

• Interpreting graphical information about bond length and energy

• Representing covalent bonding through Lewis structures, resonance structures, and formal charge

• Determining polarity of both bonds and molecules

• Determining the VSEPR representation (shape) of molecules

• Determining orbital hybridization

Unit 2 Lecture Videos

1. Isoelectronic Series and Radii Comparison (not me - quick)

2. Lattice Energy and Structure of Ionic Solids (Ms. Barkume)

3. Electronegativity and Bond Polarity (me, but it's my Regents video)

4. Drawing Lewis Structures, Exceptions to the octet rule

5. Resonance, Formal Charge, Bond Order

6. Molecular Geometries (this one has a separate note page that you will get in class)

7. Orbital Hybridization Introduction (Ms. Barkume)

8. Sigma vs. Pi bonding

9. Delocalized pi bonds

10. In case you need an extra video for Structure of Metals and Alloys (substitutional versus interstitial), here ya go (Ms. Barkume)
