For Each Substance – ONE PER SIDE OF PAGE

  • total number of valence electrons
  • Lewis dot structure
  • formal charges (each element)
  • # central atom lone pairs / # central atom bonding pairs
  • # central atom bonding domains / # central atom lone pairs

Looking Ahead

  • we wil be adding more to these sheets moving ahead
  • you will need lots of room to add material and notes
  • if you wish to start building molecules then go ahead, be sure and take a picture of the molecule on your sheet with your name and all of the work completed.

Part 2 – VSEPR

  • use three charts [Class 29]
  • add this new info to each sheet
  • Fun Examples [LINK]
  • 1 – electron geometry
  • 2 – molecule shape
  • 3 – bond angles
  • NOTE: this work not required by the end of the long block

Homework

  • All work on this phase must be completed by the end of the long block period
  • This includes the pictures
  • Note: I will not collect this work so you can hold on to it

Homework (updated)

  • the newly added material (VSEPR shapes) will continue next class
  • this is not homework for Class 32

Upcoming

  • Note: upcoming test / quiz dates on Schoology
