4.S: Study Guide
Key Topics for TRU students taking CHEM1500
- Lewis Dot symbols
- the ionic bond; lattice energy
- covalent and polar covalent bonds
- electronegativity
- writing Lewis structures
- formal charge and Lewis structure
- resonance
- exceptions to the octet rule
- bond enthalpy
Key Learning Outcomes (Examples)
- draw acceptable Lewis structures for molecules and polyatomic ions based on formal charges and the octet rule
- identify sigma and pi bonding within a Lewis structure
- draw major resonance structures for molecules and polyatomic ions and determine the bond-orders for all the bonds
