  1. 4 ED
  2. Electron Domain Geometry
  3. Dipole Moment
  4. 6 ED
  5. Octet Rule
  1. a A quantitative measure of the magnitude of a dipole. The higher the dipole moment, the more polar is the molecule.
  2. b The arrangement of electron domains around the central atom of a molecule.
  3. c States that representative elements tend to gain, lose, or share electrons until they are surrounded by eight valence electrons (an octet).
  4. d Orbital Hybridization sp3
  5. e Orbital Hybridization d2sp3

5 Multiple Choice Questions

  1. Form when electrons transfer from an atom of low ionization energy (usually a metal) to an atom of high electron affinity (usually a nonmetal). The electrostatic attraction between two oppositely charged ions constitutes this bond.
  2. MG Trigonal Planar
    MG Nonlinear
  3. Orbital Hybridization sp2
  4. A molecule with one end having a slight positive charge and the other end having a slight negative charge due to differences in electronegativity. Arrow points towards the more electronegative element.
  5. Results from sharing electrons between two atoms, usually nonmetal atoms.

5 True/False Questions

  1. Resonance StructuresFor covalent molecules often show shared pairs of electrons (bonding pairs) as lines and unshared electron pairs (nonbonding pairs) as lines or dots.

          

  2. Electronegativity and PolarityThe greater the electronegativity difference between two atoms the more polar the bond.

  4. Ionic Bond>2.0

          

  5. IonicForm when electrons transfer from an atom of low ionization energy (usually a metal) to an atom of high electron affinity (usually a nonmetal). The electrostatic attraction between two oppositely charged ions constitutes this bond.
