PracticePg. 58 • Create a chart like the following taking up the WHOLE page
VSEPR Theory Pg. 59
Resonance • It is possible to have more than one Lewis diagram for the same compound • Called resonance structure • Ex.
Molecular shape • You can determine the shape of a molecule based on the Valence Shell Electron Pair Repulsion model (VSEPR) • Electrons repel each other and determine shape • Bond angles are predicted using VSEPR
Steps for VSEPR model • Draw Lewis Structure • Determine the total number of “things” attached to central atom • Things includes bonds and lone pairs • A lone pair counts as 1 ‘thing’ • Double and triple bonds count as one thing • Use the chart to determine the molecular shape • Ex. CH4 and H2O
Pg. 60 • Attach a page to page 60 so that it is side by side with it. Make the following chart
