Which is the stronger acid: H-F or H-I?
 
  A) H-F, because the electronegativity of fluorine is higher than that of iodine making the H-F bond more polar and more likely to release the hydrogen ion to solution.
  B) H-F, because acid strength for binary acids decreases down the group of the periodic table.
  C) H-I, because iodine releases the hydrogen in order to form (s) at room temperature.
  D) H-I, because the H-I bond is weaker and so it is easier to break to form hydrogen ions.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
