  • Bond angle
  • الجزيئات
  • Molecular Geometry
  • Electron Geometry

Sample Learning Goals

  • Recognize that molecule geometry is due to repulsions between electron groups.
  • Recognize the difference between electron and molecular geometry.
  • Name molecule and electron geometries for molecules with up to six electron groups surrounding a central atom.
  • Compare bond angle predictions from the VSEPR-based model to real molecules.
  • Describe how lone pairs affect bond angles in real molecules.
