Hi John! I didn't specify the author's real name or pseudonym  - maybe 
that should have been worth bonus bonus points!

Subject: [TN] NTC Friday Element Quiz - The Answer

Hi folks - here is the Friday Element Quiz Answer.

The Question:

This element was first refined from ore over 2500 years ago. Its 
ionization energy is the highest of all of the metals and thermal 
conductivity is approximately 50X lower than copper. This element is 
extremely toxic yet has wide, long term industrial applications. World 
production of this element in 1971 was 10,400 tons but was only 1490 tons 
in 2001. What element am I?

Bonus points: Name the author who's fictional character was well 
acquainted with this element


The Answer:

The element is Mercury - Hg. The number of people who have actually 
"played" with Mercury and shined up coins is amazing considering how toxic 

the element is and how long it took before the dangers were realized. My 
"old" physics professors used to have vats of Hg which they used in class! 

The use of mercury in dental amalgams is still a very controversial topic 
for some folks. 

The winner of this week's quiz is Bev Christian of RIM with Mike Fenner of 

Indium running second. The answer to the bonus points was Lewis Carroll - 
the Mad Hatter character from his Alice's Adventures in Wonderland story 
has true life roots in the use of mercury in a hatter's shop.


Have a great weekend.
