Vocal quintets

For some reason, I really like words and phrases that contain all the vowels (a, e, i, o, and u) exactly once, and no other vowels. Like “pandemonium” or “Greg Louganis” or “South Vietnam” or “cauliflower.” They seem complete and self-sufficient, yet…thrifty.

What are the only such items in each of these categories? Remember, only five vowels, one of each, and no y’s allowed.

  1. Best Actress Oscar winner
  2. World nation (complete name, a la “Russian Federation” or “United States of America”)
  3. Element of the periodic table
  4. Billboard Hot 100 #1 single
  5. Birthstone
  6. Sports franchise, past or present (in one of the four major North American leagues)
  7. Book in The Novel 100: A Ranking of the Greatest Novels of All Time
  8. U.S. Cabinet department (Department of _____)
