Hi folks - the answers:

1) What element has been discovered "twice"? First in 1841 and second in 
1896. Bonus points if you can name the 1841 and 1896 scientists that made 
the discoveries.

Uranium (U) = 1841 by Peligot and 1896 by Becquerel

 (reference - Structure-Property Relations in Nonferrous Metals by Russell 
and Lee)

I have severely underestimated the Technet community - many, many folks 
had the correct answers very quickly. I'll make the next question a bit 
tougher. Have a good weekend!
