Tuesday Night Trivia

Tonight, a two parter involving the Periodic Table:

1. Two vowels are not symbols for elements on the Periodic Table. Name them. (I count "Y" as a vowel.)

2. 14 symbols for elements on the Periodic Table are single letters. Almost all of these letters are initials for the English-language name of the element they represent. Two are not. Name them.

To clarify part 2: Were "scrambium" an element represented by the symbol "Z," it would be one of the answers.
