For each of the following molecules or polyatomic ions, complete the following:

  1. Write the formula on a piece of paper.
  2. Calculate the total number of valence electrons and enter it in the blank provided.
  3. Neatly draw the Lewis structure on the paper. (If there are resonance structures, include them all.)
  4. Determine the molecular geometry and enter it in the blank provided.
  5. Based on the molecular geometry, enter the optimal bond angle. (e.g. 90, 109.5, 120, 180)
  6. Use electronegativity values to determine if the bonds are polar or nonpolar. (Enter "polar" or "nonpolar" in the blanks provided.)
  7. If the bonds are polar, draw a modified arrow ( +----> ) above each bond in the Lewis struture, pointing to the more electronegative element.
  8. Determine if the overall molecule is polar or nonpolar. (Enter "polar" or "nonpolar" in the blank provided.
