CH33 – Bond Polarity

Crystal Lattice

CRYSTAL LATTICE = NOT A MOLECULE

Dates

  • P4 – Monday, November 13th
  • P5 – Monday, November 13th
  • P7 – Monday, November 13th

Quiz – Lewis Structures

  • one formula
  • total valence electrons
  • Lewis structure
  • Formal charge on each atom

Electronegativity

New Idea – Bond Polarity [Presentation]

    • Not a crystal lattice (see above)
    • Unequal sharing of electrons
    • this “pull” = electronegativity
    • PT trends – which type of element pulls more? less?
    • There is a number
    • Show on 3D version of molecule
    • How do they add up?
    • examples! BI3, CHCl3, HOCl, BrF3

 

Homework

  • Chapter Notes: 8.1-8.3
  • PDF to Schoology
