For 2019-2020 Year, Chapter 8 and Chapter 9 (this is one we were finishing before we went to Remote Learning).

Topic 2.1 Types of Chemical Bonds
- Electronegativity differences between two atoms influence how valence electrons are being dealt with between the two atoms

Topic 2.2 Intramolecular Forces and Potential Energy
- Especially look at Interatom distance and Potential energy graph to explain bond length when sharing valence electrons (length where less energy location). Fig 8.3 Pg 342

Topic 2.3 Structures of Ionic Solids
- Need to Coulombic law ( I call it Coulombic force) & Lattice Energy and how it affect bonding and ion properties
- Be able to explain Energy Effects in Binary Ionic Compounds (I believe it use to be called Born-Harber Cycle) Fig 8.11, Pg356

Topic 2.4 Structure of Metals and Alloys
- Explain how valence electron are being dealt with between atoms ("sea of free flowing valence electrons or "delocalized" electrons)
- Section 10.4 in book but not Bragg Equation

Topic 2.5 Lewis Dot Structures (LDS)
- Be able to do LDS for various covalent bonded substance (Molecular compound & Polyatomic ions)

Topic 2.6 Resonance and Formal Charge - Self explanatory

Topic 2.7 VSEPR and Hybridization - Self explanatory
