5 Matching questions

  1. Dipole Moment
  2. Covalent Bond
  3. Nonpolar Covalent Bond
  4. Ionic
  5. Electron Domain
  1. a A quantitative measure of the magnitude of a dipole. The higher the dipole moment, the more polar is the molecule.
  2. b >2.0
  3. c Results from sharing electrons between two atoms, usually nonmetal atoms.
  4. d A bond in which the electrons are shared equally between two atoms.
  5. e A region around an atom in which electrons will most likely be found. Produced by a nonbonding pair, a single bond, a double bond, or a triple bond.

5 Multiple choice questions

  1. 1.0-2.0
  2. A bond in which one atom attracts the pair of electrons more strongly than the other atom.
  3. H is never the central atom.
  4. Orbital Hybridization d2sp3
  5. Hydrogen provides an exception to the octet rule because it requires only two electrons to attain a noble gas configuration.

5 True/False questions

  1. Ionic BondAn attractive force between ions of opposite charges, often a metal cation and a nonmetal anion.

          

  2. LatticeA stable, ordered, solid three-dimensional array of ions associated with ionic compounds.

          

  3. Drawing Lewis Structures1) Total the valence electrons of all bonded atoms. (- means you add electrons, + means you subtract electrons)
    2) Use one pair of electrons to bond each outer atom to the central atom.
    3) Complete the octets around all of the outer atoms.
    4) Place any remaining electrons on the central atom.
    5) If there are not enough electrons to give the central atom an octet, make multiple bonds.

          

  4. Octet RuleStates that representative elements tend to gain, lose, or share electrons until they are surrounded by eight valence electrons (an octet).
