The elements are the building blocks of chemistry and the building blocks of this week's quiz. These dozen questions are effectively multiple choice with over a hundred choices, but to be nice each question restricts the possibilities for you. For fun, there's a bonus answer hidden somewhere, worth another twelve points if you can find it (mostly useless hint: it has nothing to do with science).

Thanks so much! I am in the planning stages for a chemistry class and wanted to give the students a question per week for 14weeks.
Excellent. There are plenty of other chemistry questions in the blog if you poke around. It's always great when trivia is used in a non-trivial manner!
