| At first I thought it was elements that started with the letters in question, but then I realized it was letters that contain the letters in question. Perhaps it should say "contain" rather than "with" to point this out better. On the other hand, I may have just screwed up, so perhaps this isn't worth doing. Good quiz overall. I agree that Wolfram should be a bonus answer. Also, I probably would exclude ununhexium, as if you include it, you really could include an infinite number of elements since there is an infinite number of placeholder element names with the "hex" part in it, even if they aren't currently represented on the existing periodic tables. |
