Lewis Structures
2
Localized Electron Bonding Model (LE)
Assumption: a molecule is composed of atoms that are bound together by sharing pairs of electrons using the atomic orbitals of the bound atoms.
3
Localized Electron Bonding Model (LE) Parts
Description of the valence electron arrangement using Lewis structures Prediction of the geometry using the valence shell electron-pair repulsion (VSEPR) model Description of the type of atomic orbitals used by the atoms to share electrons or hold lone pairs
4
Lewis Structures What is the most important requirement for the formation of stable compounds? Answer: The elements achieve noble gas electron configurations This requirement applies to both ionic compounds and covalent molecules!
5
Review Lewis Structures
Write Lewis dot diagrams for the following: K Br K+1 Br-1 F Fluoride ion (Draw ionic/covalent diagrams to show lone/bonding pairs.)
6
Steps for Writing Lewis Structures
Found on p.376!!! Examine examples on pp Expand: What is the configuration for HCN?
